Lack of binocular inhibition in monocular segment of lateral geniculate nucleus of rabbits

In the monocular segment of the rabbit lateral geniculate nucleus, relay cells responded exclusively to the contralateral optic input with an EPSP-IPSP sequence. The ipsilateral optic input could neither evoke PSPs nor facilitate the PSPs from the contralateral eye, indicating the absence of binocular inhibition in the segment.
