title: Binocular properties of lateral suprasylvian cortex are not affected by neonatal corpus callosum section.
abstract: The lateral suprasylvian cortex (LS) was physiologically examined in cats with neonatal section of the posterior corpus callosum (CC) at 2 or 3 weeks after birth. All receptive field properties of the LS cells, including ocular dominance, were found to be normal, despite a reduction in binocular activation in area 17 in the 2 week CC cats. Therefore, binocular activation of LS cells is not dependent on callosal input at any age, nor is it dependent on normal levels of binocular activation of striate cortex.
