The authors recorded 19ch event-related potentials (ERPs) during binocular stereoscopic vision by random-dot stereograms (RDSs) from 9 subjects. The stereoscopic vision was invoked by three kinds of RDSs with middle-sized, large, and no disparities. The subjects with liquid crystal glasses were requested to press a button when the stimuli were stereoscopically perceived and to press another button without stereopsis. From the multiple equivalent current dipole source localization (ECDL) of differential waveforms between middle-sized or large, and no disparities, it followed that ECDs for components with negative peaks at 400ms were located at the parietal cortex, and that those for earlier components with a positive peak at 100ms and a negative peak at 250ms were localized to the striate and prestriate cortices, respectively.
