Key findings

  • Groups differed in total theta and high beta
  • Frontal alpha asymmetry alone did not separate depression cleanly

Healthy adults and patients with major depression were grouped by the direction of their frontal alpha asymmetry, then compared on resting EEG. The groups differed in total theta and high beta, with depressed patients showing lower total theta, which may refine how frontal asymmetry is used as a biomarker.
