We quantified lower alpha band power (8-10 Hz) in 20 patients with obsessive-compulsive disorder (OCD) and 20 matched healthy controls during blocks of rest and presentation of neutral, aversive, and OCD-related pictures. Compared to the control group, OCD patients showed altered asymmetry, with frontal alpha power… CONTINUE READING
