[Effect of parameters of spatio-structural stimuli on evoked potentials of the visual and posterior associative regions of the cortex in man].

In subjects with normal vision, differences have been detected in the reactions of the main components (P100, N150, P200) of evoked potentials recorded in the Oz and TPO leads, to homogeneous stimuli, chess fields with different sizes of cells and grids differing in area and the number of orientation stripes. The data obtained are discussed in the light of V.D. Glezer's hypothesis on specialized information processing in the visual and posterior associative cortical areas and concepts on the existence of separate channels of processing different image properties.
