ROI Analyses – Study 2 Amygdala activation during anticipation is related to anticipatory time Parametric modulation of the exposure time to a salient pain cue resulted in a highly significant increase of activation within bilateral amygdala compared to that during RT ( Fig. 2B ), i.e., amygdala activity increased during PAT in direct proportion to the duration of the PAT (right: 22/-6/-10, t(11) = 4.2, p<0.01; 576 μL; left: -25/-5/-10; t(11) = 4.2; p<0.01; 448 μL).
