Correlations between changes in frontal alpha EEG asymmetry (FAA) during the rtfMRI-EEG-nf training and individual psychological measures. The individual FAA changes between the Rest and Happy Memories with rtfMRI-EEG-nf conditions (H vs R) were averaged across the four nf runs (PR, R1, R2, R3). The results are for the experimental group (EG), with each data point corresponding to one participant. A) Correlations between the FAA changes and severities of depression and anhedonia, assessed before the session. B) Correlations between the FAA changes and changes in state depression and total mood disturbance. The state measures were assessed both before and after the session, and their changes (after vs before) are included in the figures.
