Figure 6. Timecourses Extracted from Peak Voxels Displaying Late Positive Correlation Between Percent Signal Change for Unexpected Fearful Faces and Valence Bias Scores.

Figure 6

Prefrontal and subcortical areas included A) left and B) right ventromedial prefrontal cortex, C) left subgenual cingulate cortex, and D) right caudate. These timecourses illustrate that Fear Fast Responders (dark red lines) had more activation than Fear Slow Responders (light red lines) in these ventromedial prefrontal and subcortical areas late (i.e. 10 and 12 s post-cue, 6 and 8 s post-face) in unexpected fearful face trials. It is interesting to note that although these peak voxels were significant for the positive correlation between Valence Bias scores and percent signal change for unexpected fearful faces, these peak voxels also displayed an early (i.e. 2, 4, and 6 s post-cue) trial enhancement for Fear Slow Responders (light blue lines) compared to Fear Fast Responders (dark blue lines) for expected neutral faces.
