Note: Location, volumes, and coordinates from Talairach and Tournoux (1988) for the center of mass for areas of activation. Significance criteria: Arousal modulated t-test (N = 21); t[20] > 2.84, p < 0.05 (corrected), d = 0.62. Pearson correlations (N = 18 due to 3 SCR non-responders) between amygdala activity and SCR were conducted across subjects on the combined (i.e. average of negative, neutral, and positive) threat response.
