Abstract
We performed fMRI on the human parieto-occipital cortex in order to identif y the neural processing regions of stereopsis. Visual stimulation for stere opsis was performed with random-dot stereogram displayed in the image guide s of a new binocular visual stimulation device that we developed. Interesti ngly, regions from the dorsal portion of the occipital lobe to the superior parietal lobule were activated by binocular disparity, while the inferior parietal lobule was not activated. Moreover, these regions were shown as do minant in the right hemisphere. Functional brain mapping revealed that the processing regions of stereopsis were dorsally located in parietooccipital cortex, and that the superior parietal lobule is an important region for ne ural processing of human stereopsis.
