I've heard people talk about binaural beats before, but always brushed it off as pseudoscience. > The noninvasive treatment induces brain waves called gamma oscillations. Is this true? Does anyone have a link that explains these brain wave patterns in layman's terms? What exactly is happening to my brain when listening to these sounds?
