Mean transient responses to negative versus neutral pictures. (A) The left and right amygdala responded more strongly to negative than neutral pictures. Image threshold P < 0.05, whole-brain corrected. (B) Timecourse of right amygdala (x = 24, y = −1, z = −20) response to pictures as a function of valence and predictability. Timecourse values were derived from FIR parameter estimates; error bars denote standard error of the mean. (C) Greater IU predicts exaggerated right amygdala response to negative pictures when embedded within unpredictable timings. Gray curves denote 95% confidence interval.
