Topography of commissural fibers of the prefrontal cortex in the rhesus monkey.
The topography of commissural fibers of the prefrontal cortex was studied in the rhesus monkey using autoradiography. Commissural fibers originating in the medial prefrontal and the caudal orbital regions course through the anterior portion of the genu and the rostrum of the corpus callosum, while those from the arcuate concavity travel at the rostral border of the body of the corpus callosum. Fibers emanating from the peri-principalis region occupy an intermediate position in the genu of the corpus callosum.
