X-Message-Number: 10693 Date: Wed, 4 Nov 1998 07:06:16 -0500 From: Thomas Donaldson <> Subject: CryoNet #10688 - #10692 To Jan Coetzee: I'm glad that you are quoting sources now, because the sources matter. For brain cells, these two scientists are only 2 among those who have been working for some time in this area; nor did their work require the discovery that brain cells can form in living human brains. It's been known for some time that stem cells (from the lining of the ventricles of human and other mammalian brains) can be induced to turn into neurons. Until the recent discovery, a substantial number of neuroscientists believed that in a living adult human brain, these cells only turned into glial cells. Naturally I'm glad they're doing this work, and glad that it is moving into clinical use, if only in Parkinsonism. Replacing those neurons involved in storage of our memories, however, will be a harder task. Perhaps these methods can be suitably modified with a bit more technology to do that, too. (I have a speculative article in PERIASTRON on just this topic, but it only provides a sketch of a method and does not claim to provide more). Best and long long life, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=10693
