Neurofeedback and brainwave entrainment can both help maximize brain function.
Neuroplasticity of the brain is a topic that has been in the news a lot lately. MRI imaging has opened many new doors to our understanding of exactly how the brain works. Research shows that we have far more ability to change brain function than was previously thought possible. Neurofeedback and brainwave entrainment (BWE) are two of the powerful tools available to do just that.
Background
Neurofeedback and brainwave entrainment are each a type of biofeedback for the brain. Both employ technologies that seek to maximize brain function by altering brainwave patterns, but they go about it differently. Practitioners of each technology will argue one is more effective than the other, but regardless, increasingly, they are used in conjunction with one another to enhance the desired outcome.
Understanding Neurofeedback
Neurofeedback monitors a patient's different brainwaves with an EEG, the results of which are analyzed against a database of "normal" brainwave patterns. This is referred to as a quantitative EEG (QEEG). Based on the results, an evaluation is made, noting which parts of a person's brain are not functioning optimally. Subsequent neurofeedback training sessions target those specific areas via EEG sensors placed on the scalp. These are connected to a computer program that uses interactive signaling, through tones and computer screen images, to stimulate those parts of the brain. Basically, the brain is being retrained, and individuals have reported dramatic results.
Understanding BWE
Brainwave entrainment seeks to alter brainwave patterns by having a person listen to different sounds or frequencies through special headphones. Each ear is set up to hear a different frequency, which causes the brain to synchronize the sound by compensating through the production of special pulses called binaural beats. This, in turn, results in alterations to brainwave patterns. Different frequencies are targeted to different types of brainwaves. There are also specialized goggles available that combine variable rates of pulsating lights with binaural beats to further encourage brain synchronization. This technology is frequently referred to as audiovisual entrainment (AVE).
Applications
Neurofeedback and BWE are used for many of the same applications even though the technology is quite different. Positive results have been attained working with many learning disabilities, mental health conditions and brain injuries. This technology has also been used to enhance academic and sports performance, as well as promote calm and heightened spiritual states of mind.
Considerations
When choosing which approach to use, there are many factors to take into consideration. It is important to do your homework and get a clear sense of which approach would best meet your needs. There is a bias in much of the literature for the greater effectiveness of neurofeedback, mainly because it works specifically in response to your personal brainwaves. BWE is set at ideal levels based on the desired outcome being addressed, unless it is coupled with the use of neurofeedback. However, neurofeedback is generally a much more expensive therapy, though sometimes reimbursable through health insurance. BWE costs less and has the added advantage that it can be done at home much more easily than neurofeedback -- which is almost always done in a clinician's office. BWE also can be done in a group setting. When done properly, excellent results can be achieved with each approach. However, it should be noted that not all individuals find the therapies helpful.
