Inter-hemispheric Transfer of Meaningful Visual Information in Normal Human Subjects

Abstract

IN an earlier study¹, normal human subjects made fewer recognition responses to complex random shapes² successively exposed in opposite visual fields than to those exposed twice in the same visual field. Subjects demonstrated superior recognition of shapes exposed twice in the same visual field even though vision was allowed in one eye during initial exposure and in the other during the recognition test. As each visual field projects to the contralateral cerebral hemisphere, the results were interpreted as indicating that lateralized complex visual input does not automatically traverse the corpus callosum.
