[Characteristics of neurons of the lateral suprasylvian region of the cat cerebral cortex sensitive to the movement of black stimuli].
Visually sensitive neurons of the lateral suprasylvian area were investigated in cats with pretrigeminal brain stem sections. Nearly 25% of a neuron population responding to the visual stimuli revealed great sensitivity to movement of black stimuli across their receptive fields. These neurons were called "black-sensitive". As a rule, they had either a low-level or no background activity. Nearly 89% of these neurons revealed direction-selective properties. The most characteristic feature of "black-sensitive" neurons was a change in response patterns with the reversion of the stimulus contrast.
