Brainwave Synchronization and Binaural Beats
Binaural beats and it's occurring research actually began well over a 180 years ago, 1839, and it wasn't until the mid-1970s that binaural research began again. Recent research is applying binaural beats to a variety of different areas including physical, neurological, as well as mood enhancement and healing.
Binaural beats, technically, the processing auditory artifacts and the brains resulting entrainment. Or, two separate tones that the brain combines into one and tries to match frequency. This reaction of the brain is often measured in increased activity of Alpha brainwave, resulting in a physical aspect. Interesting, though without a physical application, the brain still reacts in a physical and measurable way.
The resulting synchronization of the brain trying to match both tones at once, increases alpha brainwave for certain tones, and increases at times, unpleasant brain waves with other tones. It's been proven that increasing Alpha brainwave activity can actually introduce an alert and relaxed state in the patient, whether it's animals or humans. This relaxed state can be used in a variety of medical ways, and is actually proven to decrease the healing time in many patients.
The binaural beat affect is used to force the brain into activity. The resulting relaxed state can be used for meditation, stress relief, and many other neurological disorders. Plenty of research is being done on binaural beats on a regular basis with the belief that by physically increasing brain wave activity, healing can occur.
With the increased research going on on binaural beats there are new methods and affects that are measured on a regular basis. Neurologically enhanced effects by using two simple tones that are less than 30 MHz apart. The human ear recognizes tones between 20 Hz and 20,000 Hz and yet brain waves are actually measured in the 40 MHz range. When the two tones are heard singly, one in each ear, the brain combines them, and then proceeds to try to match the frequency.
Beyond the stress reducing factor of a relaxed alert state, many researchers are diving into broader areas such as those for patients who are affected with Parkinson's disease. As research goes on, the applications of binaural beats can be amazing, not only is it going to use for relaxation and meditation, but it may also dive into mental disorders, and the effects that binaural beats may have on autism, bipolar disease and chronic depression, as well as schizophrenia and other neurological problems. The whole idea being that without physical stimulus, the brain waves react producing more activity within the brain itself.
It won't be long before along with meditation practices, physical therapy and mental therapy, binaural beats will be a part of a patient's health plan.
