| Abstract: | Sizes of receptive fields (RF) in areas 21, 7, and 19 of the cerebral cortex were measured in cats. No correlation between size of RF and eccentricity (average: R=0.15; p>0.05) was found in area 21, as distinct from areas 7 and 19, where size of RF increased with distance from the center to the periphery (R=0.5; p<0.01 and R=0.9; p<0.0001 respectively). Larger RF were found in the left hemisphere than in the right in field 21; size of RF also decreased and leveled out with a move away from area 21 and towards areas 7 and 19.I. P.
