Investigation of binaural beats and isochronic tones on beta and gamma brain wave frequencies / Syarifah Noor Deraman@Abd Rahman

Electrical impulses and chemical activities in human brain generate brain waves at distinct frequency domains between 0.5 and 100 Hz. These domains are associated with different brain activities and are characteristic of different mental states. The cerebral brain cells, which produce the frequency...
