An Emerging Field of Primate Social Neurophysiology: Current Developments.

Recently, there has been increased interest in investigating neurophysiological mechanisms underlying social interactions using a nonhuman primate model system. Several studies in this subfield, known as primate social neurophysiology, have begun to provide novel insights into how single neurons encode socially-relevant variables. This opinion piece intends to provide insight into the state of this field. In doing so, it discusses some common principles learned from primate social neurophysiology experiments.
