The topographical organization and laminar origin of some cortico-amygdaloid connections.
Injections of horseradish peroxidase were made into the basolateral nuclei of the amygdaloid complex in cats. It was shown that the periamygdaloid cortex immediately below the rhinal sulcus and extending medially to the amygdaloid fissure projects to the lateral nucleus. The rest of the periamygdaloid cortex medial to the amygdaloid fissure and including the cortical nucleus of the amygdala projects primarily to the basomedial nucleus. These cortico-amygdaloid projections originate in the deeper one-third of the cortex. No projections from the neocortex could be demonstrated.
