i'm assuming you are referring to the paper titled 'Neural network
models of chemotaxis in the nematode C. elegans.' . Very interesting
stuff, and thanks for the pointer. I would not, though, consider it an
upload of C. Elegans, but an emulation of one of its functions
(chemotaxing). I really haven't read anything about C. Elegans'
biology, but i'm assuming they do other things besides chemotaxing
(reproduce, for example), which are not modelled. Also, their results
for chemotaxing don't seem 'good enough' (i'm referring to the diagrams
on page 6, they obviously don't pass the nematochemotaxturing test, even
though they get close). If we are able to spot the difference from this
far away, it doesn't seem correct to me to call it a succesful upload.
