| Research Abstract |
In higher mammals, the left-right halves of the visual scene are represented separately between the hemispheres. But the corpus callosum, which is the largest commissure of the brain, is thought to play a role in ensuring perceptual continuity. Although it is crucial to understand such processes, little is known about the exact nature of the signals transmitted via the corpus callosum to single neurons in early visual cortex. Here, we isolated the callosal pathway from the thalamic ones by surgically separating the pathway at the optic chiasm. Then, responses of single neurons in primary visual cortex to thalamic and callosal inputs were quantified separately by using reverse-correlation method and compared statistically
