Experimentally, there is no such thing as an "I": take a healthy person, cut the brain in half, removing all communication between the two hemispheres, and you end up with _two_ different personalities, each one of them remembers being the former "I". I imagine that if it were possible to keep cutting with surviving remains we would get other smaller versions of "I". This is not true. First there are comunications below the cortex that are maintained even if you sever the corpus callosum (major connections betweenn the hemispheres). Many of these connections are at the level of the upper brain stem and thalamus, where all sensory input is "compiled". In addition split brain people do not act like two different people. For the most part they act like everyone else. It takes sophisticated paradigns to show the problems in communications between the hemispheres. _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
