title: Binocular stimulation reveals cortical components of the human visual evoked potential.
abstract: Dynamic random dot correlograms (RDCs) produced by a rear-projection television system elicited visual evoked potentials (VEPs) in a sample of 10 observers corrected to emmetropia. When the observers viewed the RDCs binocularly through stereo wave length filters, characteristic wave forms were recorded. Four components were reliably recorded at the onset and the offset of the correlated state of the RDCs. These components differ with statistical significance (P less than 0.05) from each other. These RDC VEPs provide a practical technique to evaluate the integrity of binocular and, by inference, cortical processes.
