caption_attribution_description: English: A mind machine, Proteus, from MindPlace.
context_page_description: A mind machine uses pulsing rhythmic sound, flashing light, electrical or magnetic fields, or a combination of these, to alter the frequency of the user's brainwaves. Mind machines can induce deep states of relaxation, concentration, and in some cases altered states of consciousness, which have been compared to those obtained from meditation and shamanic exploration. Photic mind machines work with flickering lights embedded in sunglasses or a lamp that sits on a tripod above your head or facing you. You then "Watch" with your eyes closed.
  The process applied by some of these machines is said to induce brainwave synchronisation or entrainment.
