I was discussing this with Mike Perry and he suggesed Thomas Donaldson may have an answer, and/or any other opinions from this forum are welcome. Mike pointed to a reference or sorts that shows that loss of dendritic spines occurs in senile dementias such as Alzheimer's disease. That suggest that loss of the spines occurs at the same time as loss of memory, or loss of access to the memory. I have always considered that dendritic spines are associated with memory because I faintly remember (but I can't remember the name - my spines that held this may have changed :=) ) seeing a video showing evidence of this. Does anyone know? Dave Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=15843
