I'm not a neurologist, but I very strongly doubt that human neural signals can be neatly and losslessly mapped to computer codes without simulating the actual neurons. The Blue Gene simulators aren't stupid; if they were going to get the exact same results with a logical-level sim instead of a physical-level sim, why wouldn't they have run the former one? > > -- Matt Mahoney, [EMAIL PROTECTED] > > ----- > This list is sponsored by AGIRI: > http://www.agiri.org/email > To unsubscribe or change your options, please go to: > http://v2.listbox.com/member/?&; > ____________________________________________________________________________________ Get your own web address.
