Is there some critical number >needed for "intelligent behaviour" ? I have seen any estimates quite this high for the number of neurons in the human brain. Wasserman states that there are approximately 10^11 neurons comprising something like 10^15 interconnections. More neurons than stars in the Milky Way I think. Intelligent behavior is something very elusive to discuss because it is quite difficult to quantify. Personally, I think the coastal snail shows quite a bit of intelligence but I'm not sure how many neurons it is estimated to have. dominic@debussy.cs.colostate.edu
