[Organization of the substructure of the receptive fields of neurons of the lateral suprasylvian area of the cat cortex].
The substructure of receptive fields of the lateral suprasylvian area neurons was investigated in cats. It was shown that the majority of receptive fields investigated were organized of subelements with different qualitative characteristics according to their responses to moving visual stimuli. With the unmasking method of stimulation, small amplitudes of the motion evoked, as a rule, directional responses, whereas with the masking method the same amplitude of the motion produced nondirectional responses. Some receptive fields of the investigated neurons responded vigorously to the motion of borders of the visual stimuli. The heterogeneity in organization of the substructure of the receptive fields was explained by the convergence of different inputs to the investigated neurons.
