Abstract

Binocular disparities are crucial for building an accurate three-dimensional representation of the peripersonal environment in a viewer-centred frameof reference. Previous studies have shown that visual cells of the medial superior temporal cortex (MST) have large receptive fields and that they are sensitive to disparities present in large surfaces. By using a reverse cross-correlation technique in this study we tested 175 disparity-sensitive units recorded from MST in the awake Macaca mulatta monkey to determine if these large receptive fields are homogeneous in terms of disparity sensitivity. We found that the receptive fields of 50 cells (50 out of 175, 29%) showed subregions with specific disparity sensitivity. These subregions presented eccentricities from 0.8 to 22.3 degrees and their sizes varied from 1.6to 15.3 degrees (2). This particular receptive field organization represents a suitable mechanism for encoding the location of small objects within our peripersonal space.
