Opposing effects of fear and disgust on P1 and P250/s. A, ERP waveforms at Oz. B, C, Maps of differential P1p (B) and P250/s (C), with the five sensors marked with black dots, encircled to represent Oz. D, Anxiety composite scores (anxiety severity and trait anxiety combined) positively correlated with differential P1p amplitude between fear and disgust conditions. E, F, Source estimation (LORETA) isolated the right inferior occipital gyrus exhibiting greater current density for fear than disgust conditions during the P1p interval (E) and the right fusiform gyrus exhibiting greater current density for fear than disgust conditions during the P250/s interval (F). Inf. Occ., Inferior occipital gyrus.
