Perceptual processing of stereopsis in humans: high-field (3.0-tesla) functional MRI study.
Cortical activation associated with stereopsis was studied in eight right-handed neurosurgeons professionally trained in stereoscopic vision. The activation map associated with viewing three-dimensional images, as contrasted to viewing the corresponding two-dimensional images of identical contents (images of MR angiography), showed consistent activation in the cortex adjacent to the intraparietal sulcus. The study further demonstrated a dominant role of the right hemisphere in perceptual processing of stereopsis in humans.
