An Emerging Field of Primate Social Neurophysiology: Current Developments

Schematic illustrations of the main neuronal principles discovered from primate social neurophysiology research. A, Illustrations of three different neurons encoding task events in referenced to self (self-referenced), another individual (other-referenced), or both (common-referenced). B, An illustration of a neuron whose activity is gain-modulated by different social contexts within a given reference frame. C, An illustration of a neuron whose activity is specifically gated by particular social information, such as face and eyes. D, An illustration of mirroring in a neuron with comparable firing rate profiles for experienced and observed actions and/or outcomes. Refer to the main texts for the empirical sources for these encoding schemes during social interactions.
