Contrasting Specializations for Facial Motion within the Macaque Face-Processing System

Abstract: SUMMARY Facial motion transmits rich and ethologically vital information [1, 2], but how the brain interprets this complex signal is poorly understood. Facial form is analyzed by anatomically distinct face patches in the macaque brain [3, 4], and facial motion activates these patches and surrounding areas [5, 6]. Yet it is not known whether facial motion is processed by its own distinct and specialized neural machinery, and if so, what that machinery’s organization might be. To address these questions, we used… Show more

“…Thus, two important facets of social cognition, natural motion processing and whole-animal integration, form along anatomically perpendicular axes. Only face patch AF, at the terminus of both axes, shows selectivity for both whole agents and natural facial motion (15). This convergence of streams representing complementary aspects of social agents is reminiscent of a recent theory of the human brain organization, which suggests that multiple functional pathways separately process static and dynamic animacy cues before converging at a site of integrated agent representation (35,37).…”

“…Although whole-agent integration emerges across the face patches-bolstering recent evidence that these patches represent social information beyond face form (15,36)-this integration does not develop along the same ventral-to-dorsal trajectory as natural motion selectivity, but rather the posterior-to-anterior axis of the face processing system (Fig. 5): Subadditive responses in posterior patches PL and ML gave way to additive responses in MD and MF and, eventually, a superadditive response in AF (and likely AL).…”
