Abstract: This pilot study compared the differences in the quantified electroencephalogram (qEEG) between two conditions; eyes closed resting and eyes closed listening to music of 15 subjects currently experiencing an acute psychotic episode. The results showed a significant decrease in delta, alpha and beta waves when listening to music compared to resting condition.
