No subject

I have come across a brief reference to adult neural
death that may be of use, or at  least a starting point.
The book is:

Dowling, J.E. 1992 Neurons and Networks. Cambridge: Harward Univ.

In a footnote (!) on page 32, he writes:

There is typically a loss of 5-10 percent of brain tissue with age.
Assuming a brain loss of 7 percent over a life span of 100 years,
and 10^11 neurons (100 billions) to begin with, approximately
200,000 neurons are lost per day.
