I went over this and could not find anything that is more than a rough 
estimation. Judging fronm the number of neurons in the retina to the number of 
neurons in the brain seems to be al little bit oversimplified. Neurons are not 
distributed homogeneously throughout the brain (white / grey matter). Moreover 
the density (number of neurones per volume) may vary also.

To get a real idea on the numbers iiI would like to see a paper dealing with 
sections, reconstructions and comparisons of different parts of the brain.

Kind regards
Michael
