The role of binocular disparity in the neural representation of multiple moving stimuli in the visual cortex.

ABSTRACT: A fundamental process of vision is to segment visual scenes into distinct objects and surfaces. Stereoscopic depth and visual motion cues are particularly important for segmentation. However, how the primate visual system uses depth and motion cues to segment multiple surfaces in 3-dimensional space is not well understood. We investigated how neurons in the middle temporal (MT) cortex represented two overlapping surfaces located at different depths and moved simultaneously in different directions. We recorded neuronal activities in MT of three male macaque monkeys while they performed discrimination tasks under different attention conditions. We found that neuronal responses to overlapping surfaces showed a robust bias toward the horizontal disparity of one of the two surfaces. For all ani
