You can thus supposedly control your level of consciousness, producing certain chemicals on demand, even assist an out-of-body experience. We shall see. The levels, IIRC: Beta: 14 Hz+ Alpha: 8 - 14 Hz Delta: 4 - 8 Hz Theta: 0 - 4 Hzs< brainwave - coerce brainwaves to a particular beat frequency Copyright (C) 2004 John Comeau This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
