Topic: caller identity

Social interactions play a major role in primates. They rely in part on our ability to extract relevant information from the voices of our conspecifics. fMRI studies have highlighted Temporal Voice Areas or ‘voice patches’ in the brain of humans, macaques and marmosets : these regions of cortex selectively respond to conspecific vocalizations, but little is known about how individual voice patch neurons encode vocal information, particularly on caller identity. The ‘Norm-based coding’ hypothesis from face perception research suggests that neuronal activity could be modulated by the acoustical
