An experimental study of the central gustatory pathways in the monkey, Macaca mulatta and Cercopithecus aethiops

1. The cortex at the base of the central fissure, that is the fronto-parietal operculum, represents primary sensory receptive cortex for gustatory modalities. 2. This primary receptive cortex for taste is linked to the anterior Island of Reil by short inter- and intracortical association fibers. Thus the anterior island is a gustatory association area involved in the subjective recognition of gustatory modalities. 3. The nucleus ventralis posteromedialis pars parvocellularis of the dorsal thalamus is the thalamic receptive nucleus for gustatory impulses in the macaque. 4. Fibers which originate at rostral glossopharyngeal levels from the dorsal visceral gray terminate in the contralateral mucleus ventralis posteromedialis pars parvocellularis.
