Functional Organization of Macaque V3 for Stereoscopic Depth. J. Neurophysiol. 86: 2195-2203, 2001. Recordings were made from single and small groups of cells in
prestriate area V3 of the visual cortex of the Cynomolgus macaque (Macaca fascicularis). The majority of cells in V3 were
selective for orientation and stereoscopic depth, these cells being
segregated into two sets of functionally distinct columns. Orientation
columns in V3 have been previously demonstrated; here we show that V3 also contains columns of segregated disparity-selective cells. On the
basis of its cellular properties, functional organization, and
intra-cortical connections, we propose that V3 contributes to the
processing of stereoscopic depth information and that the parietal
areas to which it projects use this information for the analysis of
object depth and three-dimensional form.
