biofeedback in Science
The technique of using monitoring devices to obtain information about an involuntary function of the central or autonomic nervous system, such as body temperature or blood pressure, in order to gain some voluntary control over the function. Using biofeedback, individuals can be trained to respond to abnormal measurements in involuntary function with specific therapeutic actions, such as muscle relaxation, meditation, or changing breathing patterns. Biofeedback has been used to treat medical conditions such as hypertension and chronic anxiety.
