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
