An audio-biofeedback system for enhancement of electroencephalographic α-activities was applied to 9 neurosis patients and 9 normal controls. In both groups, the integrated % α/sec. values in the training sessions were generally increased, and in a case of the former group, the values without biofeedback were also tended to be elevated on repeating the sessions. The fractional excretion % values of some minerals in the patient group were higher, as a whole, than those in the control group, and the values for phosphorus in an above-mentioned neurosis case were reduced being associated with an increase in the integrated % α/sec. values in the absence of biofeedback, suggesting the favorable effects of biofeedback.
