X-Message-Number: 10390 Date: Sun, 6 Sep 1998 23:35:40 -0400 (EDT) From: Charles Platt <> Subject: Electron Micrographs In a post a few days ago I mentioned that Greg Fahy created some consternation in the cryonics community in the 1980s when he presented electron micrographs of brain tissue frozen with typical cryonics protocol. This statement was inadvertantly misleading. I'm told that Mike Darwin, Jerry Leaf, and Hugh Hixon had made electron micrographs approximately two years before Greg gave his presentation, which relied in part on work done by Darwin and Leaf. I'm sorry I didn't mention this. While on the subject, I have to note the response I have received to my offer (posted here and on sci.cryonics) to send anyone a free back issue of CryoCare Report, containing an article by Mike Darwin including electron micrographs showing differing degrees of damage to brains frozen with two different cryoprotective protocols. So far, precisely one person has taken me up on my offer. I can think of four possible explanations for this meager response: 1. Everyone has already seen that issue of CryoCare Report. (Unlikely.) 2. No one bothered to read my post. (More likely.) 3. Many people assume that they wouldn't know how to interpret the pictures (in fact, this isn't true; the accompanying text provides a clear explanation, and the pictures are annotated). 4. Most cryonicists really don't care what condition their brains are likely to be in after freezing, because they are confident that the damage can be fixed at some point in the future. --CP Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=10390
