Subject: Again New Theory Offered on Memory

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.

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.
