Callosal connections of the cortical taste area in rats.
The granular and dysgranular insular subregions of the cortical taste area in rats are shown to connect anatomically with the homotopical regions in the opposite hemisphere through the corpus callosum. Cells of callosal efferents and terminals of callosal fibers were found in almost all cortical layers. The findings clarify the current understanding of the morphological substrate of callosal interactions in the gustatory system.
