Characteristics of excitation and inhibition of the receptive fields of the retina and lateral geniculate body.
The process of excitation and inhibition in the receptive fields (RF) of the ganglion cells and lateral geniculate body (LGB) of the cat were examined. The extent of the dependence of the magnitude of excitation and inhibition in RF on stimulus intensity was determined. This dependence is a power function with power indices of 0.15--0.20 (LGB) and 0.3--0.5 (retina) for excitation and 0.2--0.3 (LGB) and 0.5--0.6 (retina) for inhibition.
