Abstract
The acoustic, somatosensory and visual areas of the rat cerebral cortex were mapped in view of overlapping regions, giving polysensory evoked responses. In case of each pair of modalities overlapping areas were found between the cortical representations. The evoked potentials of two different modalities show occlusive and facilitatory interactions in these overlapping areas. In the “core” region of these areas, points with especially high values of occlusion are concentrated while at the periphery weak occlusion or even facilitation is characteristic. It is supposed that the polysensory areas interposed between primary sensory fields represent not only areas with mixed responsiveness but also stage for real physiological interactions between different sensory systems.
