[Models of the neuronal network of the lateral geniculate body]

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.
