To elucidate serotonin modulation of selective attention, 13 volunteers (21-30 years) were studied in two sessions, 5 h after either acute tryptophan depletion (ATD) that decreases brain serotonin synthesis, or control-mixture ingestion (randomized, double-blind, cross-over design). Simultaneous electroencephalogram and magnetoencephalogram were measured during dichotic listening of two concurrent trains of standard and deviant tones. Subjects counted the deviants presented to one ear and… CONTINUE READING
