(Jacobs & Snyder, 1996). Although the latter study found that men with relative left frontal EEG asymmetry displayed lower BDI scores, significant results were confined to only one site (whereas results for the present study extend across a wide region of frontal cortex), with EEG asymmetry measured on only one occasion, and the range of BDI scores in that study appeared very limited, with few men endorsing scores in the high depressive range of the present study (BDI-II scores of 21 or higher).
