Selective Neurone Death as a Possible Memory Mechanism


Department of Zoology, University of Oxford

IT is a widely deplored fact that every day many thousands of our brain cells die and, unlike other types of cell, are never replaced1,2. I suggest that this may not be a purely destructive process, as is normally supposed, but may represent a mechanism for one of the brain's most constructive functions, memory or information storage.
