Well yeah, of course -- I didn't really mean it like that necessarily.
It is valid to infer that since beta waves in the EEG correspondes
to waking conciousness then whenever other waves are evidenced (in the
EEG) that *something* has shifted internally.
The entire beta, alpha, theta, delta model of brainwaves is arbitrary
The imporatant point is that states of consciousness can be shifted
in precise ways using sound.
Sigh . . . doesn't anybody have something useful to tell me about how
binaural beats work?
