The distribution of corticopontine cells in the monkey cerebral cortex was studied. Horseradish peroxidase (HRP) was injected into the brainstem of monkeys to fill the pontine nuclei on 1 or both sides. In control animals the medullary pyramids were injected or the route, size or location of pontine injections were varied. All retrograde filled corticopontine neurons were layer V pyramidal cells. Corticopontine cells were distributed within a largely continuous area of cortex which extended from the cingulate cortex medially to the sylvain fissure laterally; from the superior temporal fissure caudally to the medial part of the frontal granular cortex rostrally. Areas 4 and 6 of Brodmann (1905) contained the highest density of filled cells. In the primary visual cortex, area 17, there were a few labeled cells restricted to the rostral portion of the upper bank of the calcarine fissure, in a region representing the lower periphery of the visual field. The results are discussed in relation to the possible functions of the corticopontine system, especially the role of the extrastriate visual areas in visually guided movement.
