Effects of gaze and emotion in pSTS field potentials. Left image: Data from an epilepsy patient display field potentials from three electrode contacts within pSTS to viewing a dynamic face changing its gaze (direct, averted) and expression (from neutral to either fear or happiness). Significant differences between averted and direct gaze (top line of plots) were seen, with largest responses for averted gaze. These significant differences could persist beyond the displayed 400-msec epoch (not shown). Emotion conditions (bottom line of plots) do not show prolonged amplitude differences post-emotion change. Two phase reversals in the potential at ∼200 msec seen across the three sites are a signal of local generators at these locations. The respective MNI coordinate locations (x, y, z) for the three electrode contacts were: Site 1: +43, −53, +9; Site 2: +48, −53, +9; Site 3: +54, −53, +9. *p < .05, **p < .01, ***p < .005, corrected-over-time Monte Carlo p values. Right: Locations of left image electrode sites appear on coronal views of the post-implant structural MRI. Reproduced with CC BY 4.0 Deed from Babo-Rebelo and colleagues (2022).
