Transfer of visual information after unilateral input to the brain

Visual callosal connections are more numerous and widespread in the association areas than in the primary visual cortex and adjoining visual areas. In keeping with this, the amount of "wrong" ipsilateral visual field that is represented in the various cortical areas of primates and cats increases as one goes from primary visual cortex to extraoccipital areas. Therefore it can be argued that transfer of unilaterally presented visual stimuli occurs mainly at the temporal and parietal cortical level.
