Conceptual framework for ERP study. (A) The posited neural framework involved in processing facial emotion. The ventral affective stream (posterior system) involves reciprocal and neuromodulatory influences between the amygdala and extrastriate-fusiform gyrus network (occipitotemporal transition). The dorsal affective stream (anterior system), includes the amygdala and higher order interactions with prefrontal cortical regions (less emphasized in the current study). (B) Schematic illustration of the time course for ERP recordings, reflecting the 200 ms baseline captured prior to Task 2 presentation and the 70–170 ms period immediately after Task 2 presentation during which P1 is recorded (O1–O2 electrodes). (C) The sequence of Task 1 and Task 2 presentation, emphasizing the relationship among Task 2 onset (following a specific stimulus onset asynchrony [SOA]), the temporal framework for ERP recordings, and the capture of P1 from occipital O1 and O2 electrodes.
