What is Neurofeedback?

Neurofeedback is a form of biofeedback training that uses the EEG (Electroencephalogram), also known as the “brain wave” as the signal used to control feedback. Sensors applied to the trainee’s scalp record the brainwaves, which are converted into feedback signals by a human/machine interface using a computer and software. By using visual, sound, or tactile feedback to produce operant conditioning of the brain, it can be used to induce brain relaxation through increasing alpha waves. A variety of additional benefits, derived from the improved ability of the CNS (central nervous system) to relax, may also be obtained.
