Threat-elicited amygdala activity. The threat-elicited fMRI signal response observed within the amygdala was enhanced by images of high arousal content (i.e. both negative and positive images; top graphs). Error bars reflect SEM after adjusting for between-subject variance (Loftus & Masson, 1994), and the asterisk indicates significant difference. The threat-elicited response within the bilateral amygdala varied with the amplitude of the threat-elicited SCR such that as threat-elicited amygdala activity increased, the magnitude of the threat-elicited SCR increased (bottom graphs). Pearson correlations between amygdala activity and SCR were conducted across subjects on the combined (i.e. average of negative, neutral, and positive) threat response.
