Neurofeedback, sometimes referred to as EEG biofeedback, brainwave biofeedback, or neurotherapy, uses real-time feedback of brain activity to effect changes in brain functions. Equipment is used to measure EEG signals given off at the subject’s scalp and amplifies those signals which are then fed back to the subject through computer displays and sound systems.

Neurofeedback has a history dating back to the 1960s when it was discovered that it was possible to discriminate and control alpha waves.  Subsequent discoveries were made that clinical conditions such as epilepsy and ADHD could be improved by the use of this technology. Over the years, the application of neurofeedback to a wide variety of clinical conditions grew as did the use of neurofeedback to optimize performance.

Neurofeedback is considered controversial by some and experimental by others, but there is a rapidly growing body of studies showing its effectiveness. Our interest is primarily in using neurofeedback to remove obstacles to optimal functioning that are uncovered by carefully conducted assessments using quantitative electroencephlography (qEEG or brainmapping). 

Here is a simple introduction to neurofeedback on Youtube by Dr. Michael Cohen.

There is an interview on Youtube with Dr. Joseph Kamiya who is credited with discovering that people could discriminate alpha brainwaves and learn to control them.  His research initiated the field of neurofeedback.

There is also a recently published bibliography on neurofeedback research.
