I suspect that this is highly oversimplistic. To configurate an accurate neural emulator, you need at least (a) detailed morphological data, and (b) information on the distribution of ion channels on the cell membranes. At least, this is the information needed by current cell- level simulators. It may be possible to reduce this requirement somewhat *if we can also take physiological measurements*, but this remains to be shown, and besides, you can get physiological measurements from dead tissue. But I wholly agree with your success criterion: > Provided I/my friends do not notice the difference between my original > deceased me and the simulation it is accurate.

Please please please take the time to dig up a reference or two for us. This could be very important, but we can't evaluate it properly without seeing some original papers. -- Joe ,------------------------------------------------------------------. | Joseph J.
