Mind Machines
A mind machine (in some countries called a psychowalkman) uses pulsing rhythmic sound and/or flashing light to alter the brainwave frequency of the user. Mind machines are said to induce deep states of relaxation, concentration and in some cases altered states of consciousness, that have been compared to those obtained from meditation and shamanic exploration.
The process applied by these machines is also known as brainwave synchronization or entrainment. More »
