Figure 3.

(A) Left: linear correlations of neural activity evoked by positive minus activity evoked by negative pictures with depression severity (Hamilton depression scale) identified a dorsolateral PFC (dlPFC) area with decreasing activity for aversive and increasing activity for appetitive picture processing with rising severity. Right: strongest linear correlations were found in a time interval between 200 and 400ms, now at the bilateral dlPFC regions (p < 0.05 at cluster level).

(B) Linear correlation of Hamilton depression scale score and right dlPFC difference activity.
