X-Message-Number: 26626 From: "Basie" <> Subject: Again New Theory Offered on Memory Date: Fri, 15 Jul 2005 15:57:46 -0400 To maintain some residue of this modification, Dr. Routtenberg proposes that the "spontaneous activity" of the brain acts to "cryptically rehearse" past events. So long-term memory storage relies on a positive-feedback rehearsal system that continually updates or fine-tunes post-translational modification of previously modified synaptic proteins. This model allows for the continual modifications of memories. http://www.medschool.northwestern.edu/newsworthy/2005L-January/memory.html ____________________________________________________________________________________ If we are merely the shapes of proteins in the synapses then duplication should be easy. On the other hand if memories are constantly rehearsed then errors will occur. Thus an eternal identity is impossible. That will make the argument whether a copy is real moot. I hope Routtenberg is wrong. Basie Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=26626
