Functional Imaging of Brain Regions Sensitive to Communication Sounds in Primates

There is considerable brain imaging evidence on the neural substrates of speech in humans, but only recently has data for comparison become available on the brain regions that process communication signals in other primates. To obtain insights into the relationship between the substrates for communication in primates, we compared the results from several neuroimaging studies in humans with those that have recently been obtained from macaque monkeys and chimpanzees. We note a striking general correspondence between the primates on the pattern of brain regions that process species-specific vocalizations and the acoustics related to voice identity.
