A new objective method is described to test binocular vision. Identical gratings are presented to each eye, but they are drifted in opposite directions. Uniocular stimulation does not produce a response, but binocular combination of the gratings results in robust visual evoked potentials. Data from cats are presented to illustrate the use of this technique.
