Abstract:
:This article demonstrates how that the effectiveness of nervous system in doing the computations essential to an organism can be based on using algorithms that are readily implemented by nervous system 'device biophysics'. Collective effects and collective algorithms that exploit their dynamics provide powerful potential for useful neuronal computations.
