The study was an attempt to specify the nature of nonvisual deficits ascribed to visual cortex lesions by many investigators. It was supposed that the nonvisual deficits reflect an impairment in spatial progression. In an evaluation of this possibility, groups of enucleated rats were subjected to unilateral neocortical lesions and tested for ipsiversive progression. The hypothesis was not supported since destruction of the visual cortex alone did not produce the effect while similar-sized, more anteriorly placed, lesions did. Moreover, there was nothing to indicate that visual cortex destruction in combination with an effective lesion enhanced the effect. The results do support those who have criticized the belief that the visual cortex carries out nonvisual functions.
