Figure 5. Medial Prefrontal Cortex Activity in Response to Reward Gain Outcomes.

Figure 5

(A) Raw time course plots of mPFC ROI activity (group means and standard error) split by outcomes (hits or misses) for +$5 anticipation trials. The period of reward outcome (out) fMRI BOLD response is estimated to correspond to 10–14 seconds during the raw time course plots [presentation of outcome and post-outcome during TRs 4 and 5 (6–10 seconds) plus 4 seconds to account for hemodynamic response function (HRF) delay]. (B) Contrast (GVNout) beta values extracted from the ROI for mPFC reward outcome activity.
