Anatomical Connectivity of the Macaque Gaze-following Patch

Reciprocal anatomical connections were found between the macaque gaze-following patch (GFP) and inferior parietal lobule, likely area PFG, with only sparse amygdala labeling.

• Why it matters: The GFP’s functional role in social attention is known, but its place in a broader anatomical network for gaze following has been unclear.
• What they did: In one monkey, fluorescence-labeled anterograde and retrograde tracers were injected into the GFP, then tracer distributions were analyzed for connected regions.
• The result: The connectivity pattern supports a circuit translating information from others’ faces into attention shifts, while showing little evidence for direct prefrontal control of the GFP.
