Stereomotion processing in the human occipital cortex.
Although a high proportion of the motion selective cells in primate motion area, MT, are disparity-selective, there is no convincing evidence for cells in this area specific to stereomotion-in-depth and the neural basis of stereomotion processing remains obscure. With functional magnetic resonance imaging (fMRI), we identify an occipito-temporal region activated by cyclopean stereomotion-in-depth stimulation, centered anterior to the human motion complex hMT+. This discovery suggests a reconceptualization of the architecture of the motion complex to incorporate the processing of motion in the third dimension.
