“The idea is that by providing the brain with a consistent repetitive signal, it will follow along (entrainment). For example, if I chose a relaxation program, the lights might flicker on and off 10 times a second. The brain responds to each of these signals, producing a 10-cycles-per-second brain wave (10 Hz), which is in the alpha frequency range associated with relaxed, internal attention. So, using this technology, you can influence the brain by encouraging it toward certain brainwave patterns, which can influence your state of consciousness…”
