adopts biological information simulation tech. and computer software technology to synthesize combined pulse wave, through the electrodes which are attached on the mastoids behind the two ears sides, and allows the therapy current to be introduced into fastigial nucleus through the skull without hurt and makes electrical stimulation on brain. The mechanism is that when the nervous pathways in the brain are stimulated by particular electric current the brain microcirculation and cerebrovascular auto-regulation will be influenced and cerebral blood flow (rCBF) will be improved.
