All primates communicate. To dissect the neural circuits of social communication, we used fMRI to map non-human primate brain regions for social perception, 2nd person (interactive) social cognition, and orofacial movement generation. Face perception, 2nd person cognition, and face motor networks were largely non-overlapping and acted as distinct functional units rather than an integrated feedforward-processing pipeline. While 2nd person context selectively engaged one region in medial prefrontal cortex, production of orofacial movements recruited distributed subcortical and cortical areas in medial and lateral frontal and insular cortex. These areas exhibited some specialization, but not dissociation, of function along the medio-lateral axis. Production of lipsmack movements recruited areas including putative homologs of Broca’s area. These findings provide a new view of the neural architecture for social communication, and suggest expressive orofacial movements generated by lateral premotor cortex as a putative evolutionary precursor to human speech. Shepherd & Freiwald examine the neural correlates of communication in monkeys during a simulated social interaction, discovering networks in the monkey brain for social cognition and social signal production, with surprising similarities to those producing human speech.
