	General soul research-One and half soul Author :Chang Kai-Chi  張開基 translation: 某君 (You are welcomed to share or reprint but please indicate the source and author) This is a very special topic in the soul research topic; the most exciting and powerful case about the formation of "soul".  if it is not the advancement of medical technology, it is really difficult to explore such deep level. Ordinary twins or multiple births, although they have the same genes, still have their own personality traits, and of course they all have their own independent "souls". However, "craniopagus twins" unexpectedly created an incomprehensible Special soul are neither independent but not identical "souls." At present, there are only six pairs of such "craniopagus twins" in the world. One pair of Iranian sisters has died in the years because of the failure of the separation surgery. When we understand such a small number of samples, we can find out. Very shocking phenomenon; Among them, the sisters of George and Lori Schappell in Pennsylvania; they are already middle-aged, and the basic personality is almost completely stereotyped, but they are not only "connected to the skull". They are very different in character. They are not like normal twins. Instead, they are just normal sisters like "non-twin". Even if they share some brains and blood vessels, even any one of them will affect their diet. To another person, but such a close physiological relationship, personality traits are still very different, the more healthy "Lori Schappell" even stressed that if she is married, the husband belongs to her alone, in other words; the husband only Can touch or like her body, can not like or try to touch George Schappell, otherwise she must divorce, never compromise. Of course, this kind of persistence is the same as that of every normal woman. There is nothing special about them. However, they share some brains and blood vessels in the " craniopagus twins". Under the "MRI" examination, they also have different opinions. Feelings and independent thinking, so if you get married, including intimacy, it doesn't affect the other side. However, the two people have different personalities, different life attitudes, different daily habits, different things, and even the body's "clear and distinct" plan. Clear boundaries, of course, must admit that they are two completely independent people, and they have their own independent "souls". It is clear that there are two different "souls", but their bodies were unfortunately connected when the mother was pregnant. There is an understandable part about the difference in personality between the sisters of the " craniopagus Twins"; that is, the physiological difference, because "Lori Schappell" is normal, and "George Schappell" has the problem of spinal bifida, so the lower body is severely atrophied. Of course, one performance is relatively strong and a relatively weak one. This is also the same in normal brothers and sisters, and dietary preferences can also be explained by different physiological conditions. However, obviously not only that, but their personality differences are also too big. Although they get along well, Lori is happy to use a special high-chair wheelchair to "carry" her sister George. Lori never complains. However, as far as personality is concerned, they are really awkward and have little in common. Suppose we separate them and compare them separately. We should find that these are two completely different people. It is impossible to see that the two are not only sisters in the same family, nor normal twins, but more difficult to resemble them. It is a " craniopagus twin" that shares part of the brain and blood vessels and is physically connected to each other to circulate blood. Then, in the cognition of "soul theory", these are two completely different souls. Obviously, they are not the "new souls" formed after birth, but the two "re-born" souls. Because, if it is the "new soul" formed after the two births, although they are also independent souls, not completely similar copy versions, but have the same genes and the same "default genetic mode"; Even from the same life background that is inseparable from 24 hours after birth, the external information and stimuli received from childhood are also inseparable. Therefore, if there are many similar parts in personality, it is very normal and reasonable, but the truth is that they are completely different in personality. Moreover, in the case of normal twins; the same genes, the same family, the same living environment background, have very similar appearance, physique, and similar personality traits, but there are still not exactly the same mind, preferences and career development. These differences may also be because they are independent individuals after all, still have their own "solitude" or the opportunity to get along with different "peers", and even at the same time, parental education or a sentence of praise for a scolding may have different effects, which are understandable. However, craniopagus twins are basically inseparable for 24 hours. They have almost no chance of being alone. There is no chance of "separate" interaction with parents and colleagues. Then, apart from the differences in physiological strength, what will form? Distinctive personality traits, even "do not recognize" the other side of the body or shared brain, blood vessels are related to "self"? Then, it should be reasonable to explain it with two reborn souls formed by the day after tomorrow. Because of the completely different personality traits, they are affected by the differences in "pre-existing personality habits." Of course, what is more relevant is another pair of still very young craniopagus twins; born in 2006 in British Columbia, Canada, Krista (R) and Tatiana Hogan sisters, found in a special "nuclear magnetic resonance" examination; their shared brain and blood circulation are more complicated and strange than the "Lori and George Schappell " sisters. For the sound and light stimulation for one of them, the other person not only has a clear reaction, but also found the corresponding part of the reaction in the brain development (this is not what the sisters of Lori and George Schappell did), and they are in daily life. The singular phenomenon is also amazing, even scientists can hardly have a clear answer; for example, each of them has a pair of eyes, one of them is watching TV, the others is watching somewhere else, not the TV. But there is the same visual response, and one of them can see the toy, and the other is clearly unable to see the toy, but she can get it with the right hand. They can share different horizons, which means that there are four eyes watching the world, and then you can see that the vision seen by the twins are much larger than of the average person is much larger (Note: this pair The sisters are connected to the side of the skull. If the hindbrain is connected, the old saying "Two eyes on the back of the header" will be true.) Even if one of the eyes is blinded, she can know what another little girl is watching. And for one of them itching, the other will laugh like the other, one for the injection, the other will cry, these various performances can prove that they have a common feeling, but they have different mind. sometimes one wants to go east, but the other wants to go west. The more healthy ones will also deceive the weaker one. Christa relies on her sister's kidney and heart to sustain her life. Once she picked up the juice and said, "I drink very fast." At this time, Tatian Na suddenly opened her eyes and held the stomach and exclaimed "No." Krista likes to eat seasoned ketchup, while sister Tatiana dislikes it most. One day, when Krista was eating ketchup very much, although Tatiana didn't take a bite, she kept making faces, as if she was trying to scrape something from her tongue. In these descriptions, we can see that they can almost share the "feeling", whether it is the one-sided "feeling" of any party, whether it is visual, auditory, tactile, taste, etc., and the other can feel exactly the same at the same time. "Message", however, this refers to the aspect of "receiving messages" as if it were "one person". In fact, this is already very peculiar; however, in "reaction", there is a big difference; (Note: for example "Multiple Fingers", assuming that there are six fingers in each hand, and they are all very flexible, then the touch or pain of any one finger, uploading or reacting is of course the same person, this is beyond doubt, including no one or the other person will treat the two extra fingers as inanimate or otherwise. However, it is difficult to define this in the pair of twin sisters. For the case of drinking juice, it should be that the "belly" is already full. However, one of the twins still like the taste of the orange juice so she continues to satisfy the mouth. This situation will occur even for a normal single person; Some people know that the stomach is already full, but it is still difficult to refuse the temptation of food. Therefore, the brain has repeatedly reminded that "the stomach is very swollen", but another "self" still wants more food. I can't help but continue to take all kinds of food and continue to enjoy the taste of the mouth and the pleasure of chewing. The difference is only; the sane self does not make a clear and specific cry; but one of the twins, could clearly express the opinion. In addition, the example of ketchup also proves that the "taste" message of the taste transmission in one of the mouths can be clearly felt when entering the brain. However, the "reaction" is bipolar, one likes, one disgusts. Well, obviously such a differential reaction, can not say that they are the same person, apparently two independent personalities. Let's assume that if they are just normal twin sisters and have no physical connections, then let them eat ketchup, one like it, one disgusts, this is nothing to be fussed. However, this pair of twin sisters did not eat ketchup at the same time, but the one of them is eating. While the other did not eat, but also felt the same taste, and subconsciously scraped the tongue, as if there was really in the mouth. ketchup. This is very strange. I believe that if it is not because the brain is connected, any two separate individuals, even identical twins, will not have such a clear "feel" and such a fierce "reaction". Assume again; if medical technology is one day more advanced, it can smoothly and safely divide the pair of cranial twins, when Krista eats the favorite ketchup food, Tatianna does not eat, then there will be disgust and scrape Does the tongue react? According to theory, their "feelings" have been separated and there should be no reaction. However, in the current state of continuous connection; they have a common "feel" or even "communication" does exist, but the reaction is very different, so even if they agree that they are physically different People, only some parts are shared, which makes sense. The following appendix cites more detailed information about the craniopagus Twins from the Internet for discussion and research: It was bedtime for Krista and Tatiana Hogan, and the 4-year-old twin girls were doing what 4-year-olds everywhere do at bedtime. They were stalling, angling for more time awake. Their grandmother, Louise McKay, who lives with the girls and their parents in Vernon, a small city in British Columbia, was speaking to them in soothing tones, but the girls resorted to sleep-deferring classics of the toddler repertory. “I want one more hug!” Krista said to their grandmother, and then a few minutes later, they both called out to her, in unison, “I miss you!” ……………………… ………………………

	Suddenly the girls sat up again, with renewed energy, and Krista reached for a cup with a straw in the corner of the crib. “I am drinking really, really, really, really fast,” she announced and started to power-slurp her juice, her face screwed up with the effort. Tatiana was, as always, sitting beside her but not looking at her, and suddenly her eyes went wide. She put her hand right below her sternum, and then she uttered one small word that suggested a world of possibility: “Whoa!” In any other set of twins, the natural conclusion about the two events — Krista’s drinking, Tatiana’s reaction — would be that they were coincidental: a gulp, a twinge, random simultaneous happenstance. But Krista and Tatiana are not like most other sets of twins. They are connected at their heads, where their skulls merge under a mass of shaggy brown bangs. The girls run and play and go down their backyard slide, but whatever they do, they do together, their heads forever inclined toward each other’s, their neck muscles strong and sinuous from a never-ending workout. Twins joined at the head — the medical term is craniopagus — are one in 2.5 million, of which only a fraction survive. The way the girls’ brains formed beneath the surface of their fused skulls, however, makes them beyond rare: their neural anatomy is unique, at least in the annals of recorded scientific literature. Their brain images reveal what looks like an attenuated line stretching between the two organs, a piece of anatomy their neurosurgeon, Douglas Cochrane of British Columbia Children’s Hospital, has called a thalamic bridge, because he believes it links the thalamus of one girl to the thalamus of her sister. The thalamus is a kind of switchboard, a two-lobed organ that filters most sensory input and has long been thought to be essential in the neural loops that create consciousness. Because the thalamus functions as a relay station, the girls’ doctors believe it is entirely possible that the sensory input that one girl receives could somehow cross that bridge into the brain of the other. One girl drinks, another girl feels it. What actually happens in moments like the one I witnessed is, at this point, theoretical guesswork of the most fascinating order. No controlled studies have been done; because the girls are so young and because of the challenges involved in studying two conjoined heads, all the advanced imaging technology available has not yet been applied to their brains. Brain imaging is inscrutable enough that numerous neuroscientists, after seeing only one image of hundreds, were reluctant to confirm the specific neuro­anatomy that Cochrane described; but many were inclined to believe, based on that one image, that the brains were most likely connected by a live wire that could allow for some connection of a nature previously unknown. A mere glimpse of that attenuated line between the two brains reduced accomplished neurologists to sputtering incredulities. “OMG!!” Todd Feinberg, a professor of clinical psychiatry and neurology at Albert Einstein College of Medicine, wrote in an e-mail. “Absolutely fantastic. Unbelievable. Unprecedented as far as I know.” A neuroscientist in Kelowna, a city in British Columbia near Vernon, described their case as “ridiculously compelling.” Juliette Hukin, their pediatric neurologist at BC Children’s Hospital, who sees them about once a year, described their brain structure as “mind-blowing.” An incomparable resource for neuroscientists interested in tracing neural pathways, in the malleability of the brain and in the construction of the self, Tatiana and Krista are also a study in the more expansive neural system of sociology: the feedback loop of how their family responds to difference, how the world outside the walls of their home responds to the family’s response and how the girls respond in turn. For now, for the most part, the girls are not treated as if they were, as one neuroscientist described them, “a new life form.” Although they rarely venture outside their home, they spend most days the way many preschoolers do, chasing after an uncle’s puppy or watching “Dora the Explorer” or testing their grandmother’s considerable patience as they play their private games at bedtime. “Now I do it,” Tatiana said, reaching for the cup from which her sister was just drinking. She started to chug. Krista’s hand flew to her own stomach. “Whoa!” she said. The girls cracked up. Louise sighed. “Girls,” she said one more time. “It is time to settle down.” ……………………… ……………………… When Felicia Simms found out about the unusual nature of her pregnancy, she was 20 years old with two small children, living on her own in a small apartment and relying on the Canadian welfare system for financial support. She still had an on-again, off-again relationship with the father of her first child, her high-school sweetheart, Brendan Hogan, but they often fought about his drinking and drug use, and he worked only sporadically, in construction or at a meatpacking plant. There are probably no two parents who would feel prepared to cope with such life-altering news, but Simms and Hogan did not have the benefit of significant resources to help them. The evening after her first prenatal checkup, Simms, who had just learned she was having twins, got a call from her doctor, asking her to come back the next day. Concerned, she brought along her mother, Louise, and a sister-in-law. There was no easy way to say this, the doctor said: the twins were conjoined. The room went silent. Then all three women wept. Simms has little recollection about what was going through her mind at that moment. She was not without a reference point: both Simms and her mother had been fascinated by documentaries about Lori and Reba Schappell, two sharp, functional women who are, at age 49, the oldest living female craniopagus twins in the United States. “I was just trying to process it,” Simms said. ……………………… ……………………… Now 25, Simms is a mother of five children: Rosa, 8; Christopher, 6; Tatiana and Krista; and Shaylee, who is 3, born a year and a half after the twins. They live together with their maternal grandparents, three cousins, an aunt and uncle and Hogan, who moved in with the family last year. When I met them, they resided in a tract house that had been subdivided into many rooms for senior living before the Hogan-McKay clan arrived. The family relies mostly on public assistance. Dinner sometimes seems to make it on the table only by some last-minute stroke of luck or resourcefulness. Simms has always appreciated what she characterizes as her mother’s easygoing ways. It was Louise who paid for her first facial piercing, at age 12, and who accepted the news easily when she learned her daughter was pregnant three years later. “We were never normal,” Simms says, and “that was O.K.” She thinks that in some ways it was easier for her family to accept the idea of conjoined twins than it might have been for a family that was more conventional. They did not have to reinvent their sense of themselves, the image they presented to the world. “In my house growing up, everything didn’t have to be perfect,” she said. “I never had to be like everybody else, look like everybody else.” Unless the twins are having a rare health crisis or are being followed by video cameras (the National Geographic Channel showed a documentary about them last year), they are part of the general background din of the house and a far less dominant issue than the pressing financial concerns. The adults of the family tend to congregate around the long dining-room table, where the girls’ grandmother runs both a delivery business and the household — directing drivers, calling out to the twins to stop teasing their little sister and planning dinner for everyone. Simms has the same coloring and smoky eye makeup of the actress Kristen Stewart, and the movie “Twilight” plays in heavy rotation at their home. A fascination with the supernatural seemed to inform even how she thought about her unusual pregnancy. “A month before they were born, I had a dream of them being born that was completely the way it happened,” Simms said, sitting at the dining-room table. “I heard them crying in my dream just like they cried when they were born. I just knew they were going to be fine.” By the time she delivered, the doctors were preparing her for the worst; social workers met with her about grief counseling. But Simms’s intuition was right: the twins were born healthy at 34 weeks, miraculously stable and in need of no major interventions. The girls stayed under observation at the hospital for two months, and soon Simms and Hogan faced another major decision — whether or not to separate them. Cochrane, their neurosurgeon, consulted with other surgeons who have separated conjoined craniopagus twins, and the team concluded, based on their experience with that kind of surgery and their analysis of the CT scans, that separation would be extremely high risk. “You’d have to have cut through too much normal tissue and split the thalami,” said James T. Goodrich, director of pediatric neuro­surgery for Children’s Hospital at Montefiore in the Bronx who was consulted on the case. “It would have potentially been lethal.” Goodrich knows from experience how unpredictable and potentially dangerous any separation of craniopagus twins is likely to be. Beginning in 2003, he performed a series of operations to separate Clarence and Carl Aguirre, craniopagus conjoined twins who were 18 months old during the first operation. Although Goodrich proclaimed their futures bright at the time of the separation, and one of the two boys is indeed thriving, his brother eventually developed debilitating seizures; the boy, now 9, takes medication that impairs his alertness and cognition. In the case of the Aguirre brothers, neither boy would likely have survived without the surgery, because the layout of their vascular systems put too much pressure on Clarence’s heart. In the case of Tatiana and Krista, however, Goodrich said, “Mother Nature, or whoever their God is, did not give them the other issues that are the problem with these kids — cardiac failure.” Although Tatiana does bear more of the burden of pumping blood for their two bodies, the vascular system is symmetrical enough that the doctors consider them relatively healthy. (Given the risks, the family opted not to separate the girls.) From the very beginning, doctors wondered if the twins shared sensation; an early video shows one girl being pricked for a blood test as the other starts to cry, her face a perfect mirror image of her sister’s. A pacifier in one mouth seemed to soothe both crying babies. Despite the interest of the scientific community, the girls, because of their age, have not experienced extensive investigation. “If one of them needs it for their health, by all means, they can do what they need to do,” said their step-grandfather, Doug McKay, who, like their grandmother, is very involved in the girls’ care. “But I’ll be damned if you’re going to poke and prod and experiment on them.” Cochrane gives the family credit for being “able to play the hand they’ve been dealt . . . and to recognize that these kids are growing and developing. And that they’re not that different from normal kids.” ‘I have two pieces of paper,” Krista announced. The girls sat at a small table in the living room, drawing, their faces, as always, angled away from each other. Each had one piece of paper. So I was surprised by Krista’s certainty: She had two pieces of paper? “Yeah,” the girls affirmed in their frequent singsong unison, nodding together. It was one of those moments that a neurologist or psychologist or any curious observer could spend hours contemplating. Was Krista using “I” to refer to both her and her sister? Is Tatiana agreeing with her sister’s assessment at a cognitive level or uttering the same word simultaneously for reasons unknown to her? Although the girls can run, play peekaboo, engage in finger play shoot’em-ups for 20-minute marathons and covet their older sister’s Zhu Zhu pets, they are both also developmentally delayed by about one year. Their delays do not surprise their doctors, given their unusual brains and the fact that the girls have been forced to develop skills other children have not. A crayon drops to the floor, and I move to pick it up, imagining how laborious it would be for them to move away from the table as one, with Tatiana leaning awkwardly to allow her sister to crouch to the ground. When I reach for it, however, the crayon is not there. It is already in Krista’s hand, as if by magic. “My foot do it!” she tells me. Neither girl could draw the letter X, but if there were a standardized test for grasping with toes, the Hogan twins would surely come up in the 99th percentile. The girls’ brains are so unusually formed that doctors could not predict what their development would be like: each girl has an unusually short corpus callosum, the neural band that allows the brain’s two cerebral hemispheres to communicate, and in each girl, the two cerebral hemispheres also differ in size, with Tatiana’s left sphere and Krista’s right significantly smaller than is typical. “The asymmetry raises intriguing questions about whether one can compensate for the other because of the brain bridge,” said Partha Mitra, a neuroscientist at Cold Spring Harbor Laboratory, who studies brain architecture. The girls’ cognition may also be facing specific challenges that no others have experienced: some kind of confusing crosstalk that would require additional energy to filter and process. In addition to sorting out the usual sensory experiences of the world, the girls’ brains, their doctors believe, have been forced to adapt to sensations originating with the organs and body parts of someone else.

	As fantastic as it sounds, there is little doubt in Cochrane’s mind that the girls share some sensory impressions. When they were 2 years old, he performed a study in which Krista’s eyes were covered and electrodes were glued to her scalp. While a strobe light flashed in Tatiana’s eyes, Krista was emitting a strong electric response from the occipital lobe, which is where images are assembled. The test also worked when the girls switched roles. The results were not published, and some neuroscientists believe that this kind of test, which measures changes in brain activity beneath the skull, is imprecise in determining what region of the brain is at play; but most would agree that any response in the other twin’s brain suggests, at a minimum, connectivity. The explanation Cochrane proposes is surprisingly straightforward for so unusual an outcome: that visual input comes in through the retinas of one girl, reaches her thalamus, then takes two different courses, like electricity traveling along a wire that splits in two. In the girl who is looking at the strobe or a stuffed animal in her crib, the visual input continues on its usual pathways, one of which ends up in the visual cortex. In the case of the other girl, the visual stimulus would reach her thalamus via the thalamic bridge, and then travel up her own visual neural circuitry, ending up in the sophisticated processing centers of her own visual cortex. Now she has seen it, probably milliseconds after her sister has. The results of the test did not surprise the family, who had long suspected that even when one girl’s vision was angled away from the television, she was laughing at the images flashing in front of her sister’s eyes. The sensory exchange, they believe, extends to the girls’ taste buds: Krista likes ketchup, and Tatiana does not, something the family discovered when Tatiana tried to scrape the condiment off her own tongue, even when she was not eating it. Even knowing about the tests and what Cochrane believed, I listened to the family’s stories with some amount of skepticism. Perhaps they were imagining it or exaggerating for the sake of a good story. Then in one of the many idle moments of the five days I spent with the family, the girls were watching television, and I absent-mindedly gave Tatiana’s foot, which Krista could not see, a little tickle. She turned to me and smiled, and then Krista spoke: “Now do me,” she said. Had she felt the sensation but wanted the emotional experience of knowing that she, too, was receiving that kind of playful attention? On another day, Simms picked up a thermometer that had been left on the kitchen table and, just for fun, placed it in Krista’s mouth. Almost immediately, Tatiana got a distant look in her eyes. “Not in mouth,” she said, sounding angry. Then she was quiet, and her focus seemed to tack hard. Her tongue, visible in her half-open mouth, was moving in an unusual way, curling. I wondered if I was imagining something. But Rosa, her 8-year-old sister, noticed it, too. “Isn’t that weird?” she said, her own blue-green eyes wide. “Did you see? The way her tongue was curled? It was in Krista’s mouth, but Tatty’s tongue was doing that.” ……………………… ……………………… In the Hogan-McKay family, the fantasy of twinship, of a loving double, runs strong. Simms insists that her daughter Shaylee is her perfect replica, identical in face and temperament — she calls her “my mini-me.” The girls’ older sister, the tiny, round-faced Rosa, told me that she and her cousin Shyann, who lives with her, “are like twins” — despite the fact that Shyann is much taller and a year older. And Christopher, a winsome 6-year-old with a Mohawk that matches his father’s, has been told that he had a twin who died in the womb. The remnants of the twin, the doctors told his mother, were absorbed into his body, leaving only an unusual hairy patch on his back that still remains, the soft fuzzy shadow of a life that might have been. “If I don’t feel like being me, I can switch to how my twin feels,” Christopher told me once, as he was playing a video game. “And if I’m mad, I can switch to how my twin feels. Then I can switch back to being me.” ……………………… ……………………… Though they frequently move in near synchrony, mirroring each other’s gestures, the girls clearly have different personalities. Simms says Tatiana is more lighthearted, that Krista is “more of the bully” — that she is moved to scratch or hit Tatiana in frustration more often than the reverse. And they look remarkably different, although they are thought to be identical. Tatiana’s heart and kidneys do more of the work for their bodies than Krista’s do, so she is smaller than her sister, frailer, diminutive like her fairy namesake; Krista has the round belly and cheeks of many a preschooler. Krista has a small dot of a red birthmark on her chest; Tatiana does not. Krista is allergic to canned corn; Tatiana is not. Even twinship, shared daily experiences and possibly shared sensory experiences do not render them one and the same. When the girls were younger, they used to try to pull their heads away from each other, Simms told me. “And I would say to them, ‘You can’t do that,’ ” she said. “I just told them: ‘You girls are stuck. You’re stuck together.’ ” Sometimes the girls would offer up that information themselves. “I am stuck,” Krista told me one afternoon, pausing as she and her sister made their way back to the bathroom, where they wanted to play with the faucets. She tapped the portion of the head that she shares with her sister. And does she like being stuck? “I love I am stuck,” she said. She smiled. She had the dreamy look of someone romantically infatuated. “I love my lovely sissy,” she said. Later that day, Tatiana announced the same thing, but she sounded more distressed, confused: “I am stuck,” she said, a querulous look on her face. She was a girl sending a message in a bottle, or from a bottle, searching for some answer to the essential question of her mysterious, still-forming mind. Later in the week, Simms was getting Tatiana and Krista dressed for a five-hour van ride on treacherous roads in the snow to Vancouver, where the girls had a series of doctors’ appointments. This time there was no fighting over the two different sweatshirts. On the rare occasions when the girls do fight, it’s painful to watch: they reach their fingers into each other’s mouths and eyes, scratching, slapping, hands simultaneously flying to their own cheeks to soothe the pain. That morning, even though Krista grabbed initially at the pink hooded sweatshirt, she ceded it easily to Tatiana, and Krista settled for the gray. “I am in gray,” she said. “And I am in pink,” Tatiana said. Something about the clear distinction may have rung some bell in Krista’s mind. She looked at her mother. “I am just me,” she said. The sentiment — assertive and profound — was hardly out of her mouth before her sister echoed her. “I am just me,” Tatiana said. The girls surely have a complicated conception of what they mean by “me.” If one girl sees an object with her eyes and the other sees it via that thalamic link, are they having a shared experience? If the two girls are unique individuals, then each girl’s experience of that stimulus would inevitably be different; they would be having a parallel experience, but not one they experienced in some kind of commingling of consciousness. But do they think of themselves as one when they speak in unison, as they often do, if only in short phrases? When their voices joined together, I sometimes felt a shift — to me, they became one complicated being who happened to have two sets of vocal cords, no less plausible a concept than each of us having two eyes. Then, just as quickly, the girls’ distinct minds would make their respective presences felt: Tatiana smiled at me while her sister fixated on the television, or Krista alone responded with a “Yeah?” to the call of her name. Although each girl often used “I” when she spoke, I never heard either say “we,” for all their collaboration. It was as if even they seemed confused by how to think of themselves, with the right language perhaps eluding them at this stage of development, under these unusual circumstances — or maybe not existing at all. “It’s like they are one and two people at the same time,” said Feinberg, the professor of psychiatry and neurology at Albert Einstein College of Medicine. What pronoun captures that? The average person tends to fall back on the Enlightenment notion of the self — one mind, with privacy of thought and sensory experience — as a key characteristic of identity. That very impermeability is part of what makes the concept of the mind so challenging to researchers studying how it works, the neuroscientist and philosopher Antonio Damasio says in his book, “Self Comes to Mind.” “The fact that no one sees the minds of others, conscious or not, is especially mysterious,” he writes. We may be capable of guessing what others think, “but we cannot observe their minds, and only we ourselves can observe ours, from the inside, and through a rather narrow window.” And yet here are two girls who can possibly — humbly, daily — feel what the other feels. Even that extraordinary dynamic would still put the girls on the continuum of connectivity that exists between ordinary humans. Some researchers believe that when we observe another person feeling, say, the prick of a pin, our neurons fire in a way that directly mimics the neurons firing in the person whom the pin actually pricks. So-called mirror neurons are thought to foster empathy, creating connections of which we are hardly aware but that bind us in some kind of mutual understanding at a neurological level. Could the girls’ connection go beyond sensory impressions to higher thoughts, thoughts as simple as “I want water” or as complex as “I’m tired of ‘Good Night Moon’ ”? The family says that the girls often get up silently and suddenly and walk over to, say, a sippy cup, which Tatiana then immediately hands to Krista, who drinks from it. I did not witness any such incident; but if it happens as described, does one girl silently express her thirst to the other in the form of a higher thought? Does Tatiana somehow experience, instead, her sister’s basic sensation of thirst, but recognize it as originating elsewhere? Is the request whispered, inaudible or incomprehensible to anyone but the sister who is so closely linked? The story of the girls drinking juice in the crib — one girl seeming to feel the other gulp — particularly intrigued Feinberg. “ ‘I felt Tatiana drink that,’ ” he said, musing on the idea of it. “Now, how crazy is that? I mean, seriously! This is beyond empathy — it’s like a metasensory experience. It’s like she has one consciousness and can witness another’s.” As profound as it is to consider that each may witness the other’s consciousness, equally striking is their ability to maintain their individuality. In his book, “Altered Egos: How the Brain Creates the Self,” Feinberg describes patients with various split-brain syndromes, cases in which the corpus callosum, the part of the brain that serves as a bridge connecting one hemisphere to the other, is severed. In one manifestation, a patient might find that one of his hands is at odds, or all-out war, with the other. The unruly hand might throw a spoon or tear up money — actions that do not originate with any desire of which the patient is aware. Yet aside from the alien hand, the patient still feels essentially like himself: such patients “act, feel and experience themselves as intact,” Feinberg writes. Feinberg says the brain labors to create a unity of experience, knitting together our partial selves via numerous cortical mechanisms into a unified whole, into a sense of self, a consistent feeling of individuality and agency. That the girls each have clear distinction, despite what he considers to be the likely leakage of sensory impressions, was telling to Feinberg. “With the split brain, you essentially cut the brain in half, yet the person feels and acts as a whole,” Feinberg said. “In these girls, they’re linked, yet each acts as a whole. It’s like a force of nature — the brain wants to unify.” To the family, questions about whether the girls are two or one are so absurd as to be insulting. They are “two normal little girls who happen to go through life sharing a bubble,” Simms said. The family sees their unusual neural connections as something “neat,” as Louise, the grandmother, puts it, providing fascinating moments they notice but hardly lie awake at night contemplating. Of far greater concern to them is the girls’ physical health. “Every day when I wake up and they’re still alive — that’s a good day,” Simms told me. ……………………… ………………………

	When the girls were younger, each experienced several seizures, which medication has since controlled. At an appointment with Hukin, their neurologist, she asked if they had any episodes recently (they had not, in more than a year), then performed a few quick tests. She put a red crayon in front of Tatiana, a purple one in front of Krista, then asked them to name the color. “Blue,” Tatiana said. “Red,” Krista said. Did they simply not know their colors? “They’re switching them,” their grandmother said; Hukin agreed it was a possibility. Hukin pulled a stuffed animal out of a bag, a turkey, and handed it to Tatiana on her right side, so that Krista could not see. “Krista, do you know what Tatiana has in her hand?” she asked. Krista paused. “Robin?” Hukin, at the time, said nothing more than “very good.” But she considered this close-enough answer extraordinary, she later told me, and took it as clinical support for the sensory connection that Cochrane’s EEG tests had revealed. Over the course of the days I spent with them, I witnessed the girls do seemingly remarkable things: say the precise name of the toy that could only be seen through the eyes of her sister or point precisely, without looking, to the spot on her sister’s body where she was being touched. But other times, the theoretical connection seemed to fail them. The family believes that making the effort to “tune in” sometimes tires them out. It’s possible that they are developing in such a way that their brains are trying hard to filter out input that originates from the other girl’s body. David Carmel, a cognitive neuroscientist at New York University, suggested that even when the girls deliver right answers, the phenomenon could be explained by something other than a neural bridge. “If they’re really close, through minute movements that one makes — maybe a typical movement her sister cannot see, but can feel — the other sister intuits the association. Maybe she associates her sister’s reaction with a robin they once liked, not a turkey.” The connection then might be scientifically mundane, but a marvel nonetheless to the casual observer. ……………………… ……………………… As I watched the girls negotiate their occasionally conflicting impulses at dinner, I thought of how my friend Peter Freed, a neuroimager and assistant professor of clinical psychiatry at Columbia, explained their possible experience of each other: “It’s as though the secretaries of Goldman Sachs and Lazard Frères have decided, without their bosses’ permission, to share certain visitors and executive memos with each other.” The executives in charge — the parts of the brain more directly involved in decision-making — would inevitably become frustrated. Every time that executive next door makes a decision, the results are “subtly influencing or altering the information the other has to work with,” says Freed, who also writes a blog called Neuroself about the construction of the self in the brain. The frustration of one executive was on full display as the evening wore on. The girls were tired. It was late for them. Someone ordered them chicken fingers, and Krista took a bite. Suddenly, Tatiana made a face. “It’s too yucky,” she said, starting to cry. The mayhem level went up a notch, and Tatiana crawled under the table, wailing, as Krista was trying to pull her back up by the force of her neck. Krista tried to put the chicken finger directly into Tatiana’s mouth. “Krista likes it!” she said. “It’s yummy!” Tatiana spit the food out, crying: “Let me hide! Let me hide!” She covered her mouth with her hand. “Don’t make her eat it, sweetie,” said their grandmother, as Doug sighed in frustration. “Sissy eat it!” Krista said again, trying to push it in Tatiana’s mouth. Krista started pulling her sister’s hair, and then both girls were crying. Tatiana’s futile declaration rose above the sounds of the restaurant. “I am getting out of here!” Tatiana sobbed. “Let me alone.” ……………………… ……………………… The girls are used to showing off their tricks (so much so that at one point, Krista put her hand on my eyes and asked me to tell her what she was seeing). And they are infinitely proud of the small things they can do that were twice as challenging for them to learn as for someone who moves independently. They like to show how they can jump up and down, which they do like any other children, or climb into their crib, which they do like self-taught gymnasts. The twins are most moving, however, when they are least aware of how profoundly different they are. One evening, shortly before the girls went to bed, I reached out and touched the tiny birthmark below Krista’s shoulder. “Don’t touch my pen mark,” Krista said. She touched the small dot of red and stroked it with her finger. Her sister, who has no birthmark there, stroked the same spot on her own body, in just the same way, drawing a line downward. She wore the same injured facial expression as her sister. Author: SUSAN DOMINUS ……………………… ……………………… Let’s discuss the twin case in Soulology"? If we agree that the "soul" is both sensible and responsive, then they are not a soul in two bodies, nor it can be said that two souls are in two bodies. The author believes that it can only be said to be a special case of "one and a half souls." Don't feel that the author is nonsense or feel that this statement is very strange, because there is no such example in ancient times? We are not sure, or because the medical science is underdeveloped, or superstitious, we have not survived smoothly, and there is no relevant research data. Therefore, we can only share this "sentimental twins" that can be shared by "feelings and minds". As an unprecedented special case, it is not only a special case of medicine, physiology and psychology, but also a special case in Soulology. At the same time, because there is such a strange case, let us determine a few things: First, the "soul" is developed the development of the body, not born to have. Second, the foundation of the development of "soul" is in the brain. Third, the connection between "soul" and physical body is beyond imagination. Once formed, it is difficult to separate during alive. Fourth, a single "soul" has its own "independent will". Even for craniopagus twins, whether or not they can share "feelings and minds", they still retain independent personality traits. Fifth, the "sense" of "soul" can exceed the "sensory cognition" of our universal human form, like the sisters of " Tatiana and Krista Hogan", sounding sound or light to any of them. Tactile stimulation, the other has the same reaction, one was watching TV, the other one was clearly not watching TV, but the other one knows what TV is playing. The vision of the two pairs of eyes exceeds the view of the eyes of a normal person, and one body can feel the pain of another body being shot... Then assume that there are " cranial quadruplets", and some of the brains are shared, and they share the same feelings and feelings. If the four pairs of eyes are just facing four different directions, if they can have a 360 degree environmental field of view, it should theoretically also hold. Therefore, when the "soul" is separated from the flesh, and the visual aspect is no longer limited by the scope of the eyes of the flesh, if it can have a wider, farther, more macroscopic and microscopic ability, it certainly makes sense. (Note 1:). In addition, a deeper level is to explore the "mind" of the spiritual level, such as happiness, excitement, anger, warmth, happiness, sorrow, panic, anxiety, sadness, pain, depression, etc. Because of the sharing of brains, there is the same "reaction"? For example, if you feel warm and happy about your parents' love, is this "feeling" exactly the same? Or if there is a difference or a completely different one, for example, one of the parties feels that the parents prefer the other, so they are angry or dissatisfied, but the other side has no such feeling at all, then the feelings of the two poles are contradictory opposites, or Can you reconcile each other? Or will they argue with each other internally? Let us assume that they can grow up smoothly, through teenagers, youth, and old age. If one of them is first in love, spiritual love, lovesickness and loved happiness, and physical instinctual sexual desire, after sharing the "feeling", will the other person enjoy the feelings of bathing in love? ? Or another lover who doesn't like sisters, will there be serious conflicts inside, a pleasant kiss, and another disgusting death, or even physical vomiting? Let’s assume that if they grow up, is it possible to develop two completely independent "souls", and that "feelings, minds" are no longer shared? I think it is almost impossible, because if they are not physiologically divided by surgery, as long as the brain and blood vessels are still in a shared situation, "feeling, mindfulness" cannot be completely blocked, or it will be shared by the Internet. In this case, we can't think of it as two independent souls; although they will disagree, for example, in action, one wants to go east, one wants to go west, then, in the end, it must be the stronger side of the physical aspect and will, and even if it is evenly matched Then, it is also a stalemate. In the end, both sides have to give up. Whether it is a body or two bodies or two connected bodies, as long as the "ideas" cannot be manipulated freely, we cannot regard it as a "complete soul." What's more, a "soul" and another "soul" have to share "feelings, minds". There is no personal privacy at all, or like the example of ketchup, they are very disgusted in their thoughts and reactions, and they cannot refuse. The message from the other party can of course not be regarded as two "independent souls". Another related question is the problem of "super-perception"; assuming that one day, the sisters can smoothly divide physiologically and form two completely independent bodies, so that long-term sharing of feelings, mindful habits and peculiar functions Is it possible to form a "phantom pain effect" that is common to amputees? Because after all, both sides have been part of their own body, and they are part of the feeling. If there is a "phantom pain" that is not unusual, it will lead to more associations: First, will "phantom pain" be more serious and more obvious than general amputees? Second, the amputee is only a part of the limb feeling "phantom pain", and the division of these two bodies, will there be a "phantom pain"? Third, if the two are separated into two places, is there any possibility of a strong "super-perception"? This problem is very practical because they have shared "feelings, minds" and should naturally be better at sending and receiving such messages. Is it possible to create an amazing "super-sensing" capability? Another related question is; if their sisters and sisters will successfully split up and become two independent bodies, then "soul"? Of course, it is not "one", nor "one and a half", but "two" independent souls. Because they are no longer physically connected, they no longer share the "sense, mind" and "soul formation" model. The network mechanism will complement each other's shortcomings; even if they have a super "super-perception", two independent individuals can still receive or reject their own switches, so of course, two separate bodies will be formed. An independent soul forms a complete two people. Note 1: When a person reappears in the form of "soul" after physical death, in fact, many abilities will be released because they are no longer bound by physical body. Therefore, we should not use the common sense to image the function of soul. To imagine the state or ability of the "soul", such as "walking, sickness, disability, loss of sensory function, hunger, thirst, addiction, reluctance, attachment, grief", etc.; however, the vast majority of souls are always inevitable persevering in the physical habits and inertia of life, and never even realizing there is no need for hungry and sleep after losing the physical body. If souls don't know anything about the possible state of "spiritual" or "post-mortem world" (usually all) then, the soul's ability can be self-limited by their own mind, and can not fully capitalize the full functions of the soul. For example, with the presence of the flesh, the "vision" of the human eyes is only 150 degrees at most, and no more than 210 degrees with the movement of the eyeballs. For many herbivores, with eyes on two sides, the vision can reach 270-300 degrees. It can be seen that the visual field of the eye is limited by the position of the eye, and it is not determined by the visual sensing area of the brain. Then, once the "soul" is out of the flesh and is no longer restrained by the position of the eyes, why must it be the same as before, or can it only "see" a 150-degree view? As far as I know, for a high-level soul, he/she could not only have a parallel 360-degree field of view, but also a 3D spherical all-round view. Here again, we must emphasize the concept of a "field"; soul It is a kind of "field". It can be called a "smart field". "Field" is actually the meaning of "influence range". For example, "magnetic field" means that the magnetic force can affect certain range with certain strength. The "soul/ smart field" also has a range and strengths. This is related to the "spiritual power" of the "spirit". The range of a “field” is normally a sphere in nature, and the "soul/smart field" is also a sphere. This is also the reason why some witnesses to the "spirit/soul" will be described by light balls or light spots., the higher the level of "spirit/soul", the "spiritual field" is not only stronger, but also larger, and can stretch Invisible "touchers" to receive or distribute messages (in fact, this is not surprising, because the most nerve cells in our brain, there are many tentacle-like "axons" that radiate to other nerve cells. of). The most realistic and most common of these luminous spheres is the image of some religions. Whether it is the Jesus, the Virgin, the saint or the Buddha in the East, the head must be bright. Aura, of course, should be emphasized on the top of the head; however, in fact, the whole is a "Sphere of independent spiritual energy".
