The extent, strength of inhibition and spatial summation property of sub-regions of the integration fields (IF) of striate cortical neurons were studied using sinusoidal grating patches drifted across the classical receptive field (CRF) and the IF. The results show that (a) the nature of integration (facilitatory or inhibitory) was the same between the two side-regions (and/or the two end-regions) of the IFs; (b) for most neuron, the exteats of the two side-regions (and/or the two end-regions) were equal or roughly equal; (c) for inhibitory IFs, the degree of inhibition at the two side-regions (and/or the two end-regions) was statistically correlative; (d) the spatial summation between the two side-regions (and/or the two end-regions) was shown to be nonlinear.
