Neurofeedback, also called neurotherapy, allows patients to visualize their brain activity in order to optimize it. During
neurofeedback sessions, patients wear hats or headbands with electrodes that monitor brain waves. Continuously updated
information from these electrodes is displayed on a computer screen so patients can immediately see when their brains are
performing more desirable activities, such as ignoring pain. The visual display constitutes a positive feedback system that
enables them to recognize and learn to consciously trigger advantageous brain states. With repetition, patients may learn
to ignore pain without conscious effort.
