Originally posted by leonheartmmI'll post some of the research when I have the time, it's quite interesting stuff. But, yes, it is definitely not well researched and is purely based off case studies to the best of my knowledge. It is a bit hard to find people willing to have their brain cut in half. There are a lot of odd psychological disorders dealing with the lack of self awareness. People failing to recognize their hand, dissociative identity disorder, etc.
not with that specific term, no. but i am familiar with the experiments done on basic cognitive functions on people with hemisphere deconnection, and even though at the basic cognitive level, the two brains can be seen as different with no way of communicating between themselves, it is still absurd to think that two different hemisphere, which specialise in different things, have different phenomenology and have no internal way of communicating between each other can give rise to stable SINGLE unified personalities which dont even feal the cognitive differences until put under special conditions. also, how can you describe the coordination of memory, language, general thinking, problem solbving at a higher level and beleifs etc, which admittedly all represent ONE person? infact i think if we take the hypothesis of the twin brains at face value, then the person wudnt be able to survive and it wud become very much like two twins in a robot each having overlapping control of it. the thing would fall down in a second. also, hemisphere deconnection in severe cases of eppilepsy etc continued BECAUSE it was seen that patients are pretty much ok even after it, the ethical impliocation of creating TWO people in one body, if that were the case, wud be terrible.also, i think, this is still one place where very little research is based{obviously becaue most neurologists would like to bruch off the question as being one of philosophy and not hard sciene} on how a single personality can remain with the currently understood mechanics of neurology and basic physics in such an absurd situation. but i see it as a very big reason to think that thing lik the holographic model/soul etc are still sumwhat better explanations for a conciousness/personality than the currently taken physical model, as it can not{in my oppinion} account for the mentioned phenomenon.
