Neurofeedback gives the brain a way to see itself

Sensors placed on the head pick up brain signals, which are then amplified. This information coming from the brain’s electrical signals is then displayed on the screen of a computer giving the brain a way to see itself in action. Neurofeedback works as if it were a mirror for the brain, magnifying areas that are not working as efficiently as they could. Please note that nothing goes from the sensors into the brain. Neurofeedback does not do anything to the organ other than teach it to work more effectively.
