Neurofeedback, also known as EEG biofeedback or neurotherapy, is a technology by which individuals learn to change the manner in which their brains function in response to realtime information based on their brains’ electrical activity, or EEG. Once learned, these changes in brain functioning tend to be long lasting, or even permanent. Research and clinical experience have increasingly come to show that neurofeedback training can alleviate, or significantly reduce, symptoms associated with a wide range of disorders and improve both the quality of life and level of performance of individuals who receive this training.
