Some quantitative hemispheric EEG measures reflecting the affective profile of students differing in university...

Quantitative measurements of the integrated epoch based EEG amplitudes obtained from two groups of university students differing in academic success during an eyes close, relaxed state revealed significantly higher right/left amplitude variance ratios and more right hemispheric non-Gaussian cumulated amplitude distributions among unsuccessful students. These data, which resemble patterns often found in depression, are consistent with, and appear to reflect specific affective differences that emerge using a concurrently administered, conventional psychometric inventory (Beck Depression Inventory) as well as a subjective self-assessment questionnaire. The results of this study may be useful in further elaborating the nature in which right hemispheric brain processes serve to mediate affective behavior, as well as influence academic performance.
