Abstract

Mathematical identification of neuron structures forming different types of receptive fields (RF) of the outer geniculate is carried out on the basis of the results of neurophysical and morphological studies. Net models of overlapping RF of different types are studied. It has been shown that the difference in time characteristics of different RF responses is mainly determined by the constants of excitation and inhibition while the difference in the character of RF response dependence on the stimulus parameters--by different types of dependence of the time of delay, on stimulus parameters and different form of spatial weight functions. It has been analysed what functional difference of neuron channels composed of various types of RF is conditioned by the differences in the parameters of neuron structures which form various RF.

摘要

基于神经生理学和形态学研究结果,对外侧膝状体形成不同类型感受野(RF)的神经元结构进行数学识别。研究了不同类型重叠RF的网络模型。结果表明,不同RF反应的时间特征差异主要由兴奋和抑制常数决定,而RF反应对刺激参数的依赖特征差异——由延迟时间对刺激参数的不同依赖类型以及空间权重函数的不同形式决定。分析了由各种类型RF组成的神经元通道的功能差异是如何由形成各种RF的神经元结构参数差异所决定的。
