Abstract
Visual responses of single units in the cortex of the middle suprasylvian sulcus were evaluated in the pretrigeminal cat. Electrode penetrations which passed through the Clare-Bishop area were in 94 percent of the cases within the stereotaxic coordinates A2 and A8. Within the Clare-Bishop area 40 percent of the units were responsive to the visual stimuli employed whereas adjacent to it only 10-20 percent responded. Correlation between receptive field size and eccentricity was poor or absent. Most receptive field centers lay within the lower contralateral quadrant. Because of the large size of the receptive fields, their scatter and individual variability, it was not possible to depict a precise scheme of retinotopical projection.
