These numbers are around since at least 20 to 25 years. I tried to figure out 
from where they are coming.... without success. Kandel was mentionesd as 
source, but in a talk he claimed nto be not guilty ;-)
I never fpoun d serious etsimations based on counting neurons in a certain 
volume or better certain volumes of different parts of the brain. Even the 2 
million neurons (or so) in bee brains are- to my knowledge- just rough 
estimates....
