Abstract:

In order to investigate the code and the mode of the potential spike in a neural system,a mode of the function bar code of the external stimulus and the spike response in a neural system is constructed by using the WinnerLess Competition model in olfactory processing networks.This mode is based on the property that all poten-tial spikes exist at the same time or no spike exists in a neural cell.It connects the external stimulus with the spike
response in a limited function bar code form ,thus presenting a theoretical cognizable mode of the stimulus and re-sponse in a neural system. Moreover,a new method to study the potential spike mode and code is proposed,which can connect the code theory and the experimental data of the potential spike together.

Key words: neural system , stimulus, response, action potential, potential spike, code
