neurons in molluscs

[Simon Lovestone]

Dear all, I'm posting this on behalf of the Science Museum in London who 
wish to know how many neurons there are in a snail, aplysia or some 
similar creature. Not my area I'm afraid but I'm sure many of you know 
the answer to this. PLease reply either to me or direct to the museum on 
r.mileham at nmsi.ac.uk  Thanks for your help
