摘要
为研究神经系统的电位发放模式和编码,利用嗅觉神经系统的WinnerLessCom petition模型,根据神经细胞电位发放全有全无的特点,构造了神经系统外界刺激、发放响 应的函数条形码模式.该模式将神经系统受到的外界刺激和电位发放响应模式用有限对 应的形式联系起来,从理论上给出了可识别的刺激响应模式.文中还提出了一种研究神经 系统电位发放模式和编码的新方法,该方法可以将编码理论和神经元发放实验数据联系 起来.
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 potential 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 response 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.
