What do researches think about why there are so many _individual_ neurons  
in the human brain (something like 10^19) ?  Is there some critical number
needed for "intelligent behaviour" ?

[It's much like asking why there are so many epithelial cells, white blood
cells and the like but I can think of a few reasons for these ...in the 
case of neurons I have difficulties].
