BiofeedbackBiofeedback is a technique using technology to monitor bodily responses such as heart rate or electrical activity in the brain with the goal of increasing performance or improving health. Neurofeedback is biofeedback using brainwaves.
One example of this is a device which provides an alert when muscles are being tensed. Through visual (a light) or auditory (a beeping noise) signals, people can be trained to relax their muscles.
There is some dispute as to whether the learning that takes place under biofeedback can be maintained once the feedback is removed.
