Functionally homologous representation of vocalizations in the auditory cortex of humans and macaques

Abstract : How the evolution of speech has transformed the human auditory cortex compared to other primates remains largely unknown. While primary auditory cortex is organized largely similarly in humans and macaques,1 the picture is much less clear at higher levels of the anterior auditory pathway,2 particularly regarding the processing of conspecific vocalizations (CVs). A “voice region” similar to the human voice-selective areas has been identified in the macaque right anterior temporal lobe with functional MRI however, its anatomical localization, seemingly inconsistent with that of the human temporal voice areas (TVAs), has suggested a “repositioning of the voice area” in recent human evolution.6 Here we report a functional homology in the cerebral processing of vocalizations by macaques and humans, using comparative fMRI and a condition-rich auditory stimulation paradigm. We find that the anterior temporal lobe of both species possesses cortical voice areas that are bilateral and not only prefer conspecific vocalizations but also implement a representational geometry categorizing them apart from all other sounds in a species-specific but homologous manner. These results reveal a more similar functional organization of higher-level auditory cortex in macaques and humans than currently known.
