Abstract

This chapter focuses on the visual information across the corpus callosum in cats, monkeys, and humans. In mammals, retino-cortical connections are such that each half of the visual field projects only to the contralateral hemisphere. The role of callosal connections is generally associated with the task of binding together the two halves of the visual field to grant perceptual continuity across the vertical meridian and/or to subserve binocular functions such as depth perception. An alternative explanation of the findings, in terms of a bilateral cortical representation of a central vertical strip of the retinae, seems to be ruled out by the results of an experiment in which reaction times were measured for the discrimination of complex gratings presented laterally or various eccentricities. If the interpretation in terms of callosal interhemispheric transfer is correct, then the psychophysical findings in humans are in very agreement with the limitations of the callosal transfer of spatial frequenc
