Mind machine
From Wikipedia, the free encyclopedia
A mind machine uses sound and/or light to alter the brainwave frequency of the user, resulting in altered states of awareness that have been compared to those obtained from meditation and shamanic exploration.
The process is also known as brainwave synchronization or entrainment.
[edit] Overview
Mind machines typically consist of a control unit, a pair of headphones and/or strobe light goggles. The unit controls the sessions and drive the LEDs in the goggles.
Sessions will typically aim at directing the average brainwave frequency from a high level to a lower level by ramping down in several sequences. Target frequencies can be in the alpha wave area in the frequency range of 8-12.
Mind machines are often used together with biofeedback or neurofeedback equipment in order to adjust the frequency on the fly.
Modern mind machines can connect to the Internet to update the software and download new sessions. When sessions are used in conjunction with meditation, neurofeedback, etc. the effect can be amplified.
