I saw the coolest thing in medical school. They were mapping a kids brain for a seizure surgery, and put half his brain to sleep at a time by injecting NaPentathol into one carotid artery at a time and doing brief neuropsych testing to each side. Wow! 17:44, 30 January 2008 (EST)

Ya there is some fascinating work done on language using this technique. I always thought it would be interesting to try it out just for fun...but probably too I am for TMS and other such procedures. tmtoulouse oppress 17:56, 30 January 2008 (EST)
I prefer to think of myself as not so much a left-brain or right-brain person but as a corpus callosum kinda guy. Oh, and I think that construction template is redundant on a wiki, isn't it? As opposed to, say, a note from an editor saying they are gonna work on an article a lot in the next few hours, so hang on before jumping in. I mean, "This article is a work in progress; feel free to either add to the article or offer input on the talk page." is a simple definition of what any article on a wiki is. humanUser talk:Human 18:13, 30 January 2008 (EST)
I've always used it as a "I'm not that stupid, hold on a minute for me!" thing.--PalMD-Did that sound a little harsh? 18:15, 30 January 2008 (EST)
I use it to try and signal that I am still doing significant changes/reorganization etc. tmtoulouse oppress 18:23, 30 January 2008 (EST)
The trouble is, that's not what it says. I think I am going to reword it as a sort of temporary "hang on while I get all my thoughts written up" kind of thing. Care to join me Template:WiP or at its talk page to improve it and make it useful? humanUser talk:Human 18:26, 30 January 2008 (EST)


This research is an argument against dualist non-materialism, but not an argument against idealist non-materialism. As an idealist, I have no problem with any of this. My belief is that when the corpus callosum is severed, the soul of the individual splits into two separate souls, one for each hemisphere; although these souls have some powers of telepathic communication with each other. If you could later repair the severing, the two souls would merge back together into one soul. --(((Zack Martin))) 23:16, 25 March 2011 (UTC)

The two hemispheres are still connected after a callosotomy by the anterior and posterior commissure, so there is communication, it's just greatly limited as the corpus callosum is the main avenue by which the hemispheres communicate. Nebuchadnezzar (talk) 23:39, 25 March 2011 (UTC)
Exactly, the anterior and posterior commissure are the means of telepathic communication between the souls occupying each hemisphere. --(((Zack Martin))) 22:08, 26 March 2011 (UTC)
There is no problem for dualism at all, but there is a problem for the most familiar version of dualism in our culture, the Christian version, imagining a single soul created with the body's conception. But that was never a fully dualist idea anyway - by what means should the material event of conception/gestation create something outside that process, a soul?
Postulate: souls/spirits are a particle entity that no material process can create or destroy that have existed throughout time. They acquire senses, hence self-awareness from engaging with their surroundings, so pre-birth souls are attracted to swarm to complexity in matter because it stirs rudimentary senses. To galaxies, then within them to solid worlds, then to living matter - and wholly unconsciously, their interaction with matter on the atomic quantum scale tipped equilibria that are otherwise not fully explained, in favour of causing matter to form into all those structures. Then, their presence in living matter both enabled + influenced brain evolution to produce a structure that could capture a soul into a dual relationship for life, the body getting the benefit of a conscious mind's abilities, the soul the benefit of awakened senses, which it retains after the body's death as is evidenced by ghosts.
Past life memories evidence in favour of pre-born souls other than ourselves being present in our bodies potentially able to tap into our senses. But their rarity suggests that, like dreams, the tapping in is usually not vivid enough to be remembered. (Memory being coded in the soul's interaction front with space.) Disorders of multiple personality indicate that with a functional lapse the brain can get into a distressing multi-soul position, and cases of total unreversed amnesia suggest a change of soul. On this hypothesis, in the split brain another soul already present in our matter becomes the embodied soul in the second hemisphere. Its language/cognitive ability varies with whether it had or had not already picked up some of that in its existence before embodiment. - Maurice Frank, Scotland. — Unsigned, by: / talk
