Study on neural mechanism of fine uncrossed disparity in 3D

Abstract

To elucidate the processes of fine uncrossed disparity in global stereopsis, event-related brain potentials(ERPs) were investigated by the detection of depth. The disparities of -8.18 arc min that was the most easily identifiable in fine uncrossed disparity and 0 arc min were selected. Results showed that there were no significant differences between ERPs to the stimuli with disparity of -8.18 arc min and ERPs to the stimuli with disparity of zero in the time windows 0-250 ms. But the differences were significant in time windows 250-400ms at the occipital lobe and reached a peak at about 400 ms at the frontal lobe and parietal lobe. So the disparity processing began at about 250 ms after the stimuli presented and reached a peak at around 400 ms in our brain.
