X-Message-Number: 3780 Date: 02 Feb 95 02:03:37 EST From: Mike Darwin <> Subject: CRYONICS: nonbrain identity Mike Price challenges me on my notions of "non brain identity." I cannot provide specific references, but I may take the time to look things up. To sum what I was trying to say: you can bet your sweet life that a concert pianist or a typist or anyone who does skills oriented things not only makes changes in their central nervous system, but in their peripheral nervous system as well. As is often said amongst craftsment and surgeons: the hands also teach the brain and learn from it. The structure of the peripheral nervous system is no doubt as partially random in its development as the structure of the CNS. Thus, great skill in acrobatics or music or whatever may not reside solely in the brain but also in other structures who's derivation during embyrogenesis, birth and growth are unique and will be lost upon discarding. Genetically identical cows do not have spots in the same places. Bodies are likely to be sojewhat different. For most people it probably won't be a big deal. The point I was trying to make is that there is almost certainly information in the body which influences behavior, feelings, etc that will be LOST when going neuro. As an extreme example, think of someone who due to his/her mother's drug use get's born with a slightly higher adrenal output than his genes would indicate. This affects his behavior his whole life long, but in these primitive times no one even notices. Then he gets neuroed and comes back with a body rebuilt from his DNA. He now feels different, acts different. Is he the same? I suspect that there are many environmental factors which effect the body (including uterine environment) in ways which then in turn impact the brain. The INFORMATION about these things is not in the genes, may not even be in the brain, but in the body alone. Thow 'em away and you won't get 'em back. Is a big deal? Not for me, but is for others, lots of intelligent others too. Jerry Leaf was staunchly whole body in part for this very reason. My post was just to point out that I think such non-brain, behavior influencing information is likely to be lost by neuros. I didn't say that it was a problem for ME. But then, as time has gone on I've learned to respect more how other people feel, particularly if there is little rational way to bound the problem. As to the nervous system: when you cut the cord you cut pretty much everything except for the vagus nerve and a few others. There is no evidence these impact on the ability to walk and their innervating functions are pretty well understood. A cord cut is REAL brain disconnector except for the neuroendocrine feedback between brain and body about which we are only now learning.
