alpha-wave training

a type of neurofeedback training that aims to teach individuals how to achieve a state of peaceful wakefulness and relaxation by increasing alpha-band activity (alpha waves). The technique usually involves alpha neurofeedback (formerly called alpha biofeedback), the process of providing a feedback stimulus (typically an auditory tone) when alpha waves appear over the occipital cortex on a scalp electroencephalogram. The efficacy of such training is disputed. See also alpha state.
