They are looking for Digital Nurosynaptic solutions. Traditionally it has been Analog. Can someone explain how would it work out?
(In analog domain, your resolution is limited by SNR, in digital, it's limited by number of bits).
As far as I know, our neurons are belived to have analogic interfaces, thus they could not be interfaced by a digital circuit. If somebody found out that they are digital, that'd be very newsworth, at least for me.
