Perceptual history influences neural responses to face and body postures.
We show that under natural viewing, the responses of cells the temporal lobe of the macaque to the sight of static head body postures is controlled by the sight of immediately actions. Cells in the anterior part of the superior sulcus responded vigorously to the sight of a face or posture that followed a particular body action, but not when it followed other actions. The effective action or posture presented in isolation or in different sequences failed to produce a response. Our results demonstrate that cells in the temporal cortex could support the formation of expectations about impending behavior of others.
