Abstract:
Interacting with objects often requires determining their 3D spatial orientation based on visual information. In this talk, I present electrophysiological data showing that individual neurons in the caudal intraparietal area (CIP) of the macaque monkey visually encode all three rotational degrees of freedom describing an object’s 3D orientation, and that all spatial orientations of a planar surface are equally represented by the population. Strikingly, I show that the relative contributions of texture and disparity cues to CIP orientation selectivity varies with surface orientation in precisely the same way as human perceptual judgments, reflecting orientation dependent changes in visual cue reliability. These results suggest CIP provides the neural basis for a cognitive map of 3D object orientation.
