Brain Wave Entrainment and Pulsed Electromagnetic Fields (PEMF)
The frequencies of naturally occurring electromagnetic signals circulating in the Earth’s ionosphere have determined the ‘evolution’ and operation of the human brain since the beginning of time. Brain wave entrainment originated and was made popular by the binaural beats community (see AlphaLearning™) and light and sound devices to stimulate the brain.
The goal of brain wave entrainment / binaural beats is to favorably affect the electrical activity in the brain (as measured by electroencephalogram – EEG or magnetoencephelogram – MEG) via non-invasive external stimuli thereby beneficially affecting the subject’s frame of mind, to enhanced learning, relaxation, etc.
