**3.8 Frontal alpha asymmetry**

Frontal (F8–F7) alpha asymmetry (fAA) is reported to be a qEEG marker for negative emotions. In the same cohort, we previously reported significant negative correlation between the magnitude of F8–F7 frontal alpha asymmetry and "depressed" score on an individualized self-inventory (ISI), purported to be indicative of negative perceptions of a person's psychosocial interactions. No significant correlations were found between the ISI and the exam scores.

**Figure 3** shows representative qEEG maps from the subject with the highest "depressed" ISI score (upper panel) and from the subject with the lowest "depressed" ISI score (lower panel).
