Abstract: Ninety-one single units were recorded in area MSTd of anesthetized and paralyzed macaques. Receptive fields (RFs) were mapped quantitatively using small patches of moving random dots in 25 different positions (the two-dimensional position test, or P2D). The dimensions of the receptive fields (RFs) were estimated by fitting P2D data with a generalized Gaussian function. The half-height areas of the RFs in MSTd were found to average 1085 deg2 and were not dependent upon eccentricity, in contrast to those in MT/V5 (n = 295) which averaged 31 deg2 at the fovea but at the periphery approached the RFs of MSTd in size. The RFs of some MSTd neurons extended 30-40 degrees into the ipsilateral hemifield. In comparison, the overlap was only 10-15 degrees in area MT/V5.
