Summary of auditory-related projections in the monkey and cat. (A) Projections from auditory cortex to auditory-related areas in frontal, orbital, parietal, occipital, temporal and cingulate cortex, as well as amygdala and striatum (not shown). (B) Projections from auditory cortex to auditory-related areas in comparable areas of the cat left hemisphere. In both species, connections with auditory related areas of cortex mainly involve the belt and parabelt areas, whereas connections with the core are sparse. Topography is evident in the connection patterns between auditory and auditory-related areas, especially along the caudal-rostral axis in monkeys dorsal-ventral axis in cats. Connections between most cortical areas are reciprocal. Projections to the amydala and striatum are not.
