[Disinhibitory zone of the striate neuron receptive field and its sensitivity to the cross-like shape].

Sensitivity of 84 neurones to presentation of cross-form figures was studied in cats as well as the lever length function prior to and after stimulation of the RF disinhibitory zone. Responses to lever length of the cross-sensitive cells were augmented in simultaneous stimulation of the RF. The data obtained suggest involvement of the end inhibition and its blocking by a side-disinhibitory zone of the RF.
