Devices and techniques that measure or influence mental and physiological states, such as neurofeedback, biofeedback, isochronic tones, the isolation tank, the hypnoscope and the so-called God helmet. An invention belongs here when its cited article describes an apparatus or method used to monitor, train or alter brain activity or bodily state. It excludes ordinary diagnostic recorders and surgical implants. Some are accepted clinical practice and others remain experimental or disputed, and the cited article states which.

Neurofeedback is a form of biofeedback that uses electrical potentials in the brain to reinforce desired brain states through operant conditioning.
Biofeedback (Wikipedia)
Has Member: Biofeedback, LeadQuote, Has Member: Biofeedback, Lead
Biofeedback is the technique of gaining greater awareness of many physiological functions of one's own body by using electronic or other instruments, and with a goal of being able to control the body's systems at will.
Isochronic tones (Wikipedia)

Isochronic tones are regular beats of a single tone that are used alongside monaural beats and binaural beats in the process called brainwave entrainment (synchronization of brainwaves).
