A Review of Mind Machines

Mind machines are tools that help you enter altered states of consciousness (also called neurotechnology, or psychotechnology). Primarily, the term “mind machine” refers to light & sound machines, but also includes a broader range of tools for biofeedback , sleep, dream enhancement and binaural beat technology like Hemi-Sync. These cutting edge devices are rapidly becoming tools of choice to explore beginning or advanced meditation, self hypnosis, sleep and dream enhancement, learning, consciousness expansion, or stress management just to name a few.

Light and sound machines produce specific, rhythmic pulses of light and sound patterns which can be perceived as complex colors, shapes or even feelings. We know the human brain has a certain rhythm when relaxed, another rhythm when focused, and so on. During a light and sound session, your overall brain rhythms, or frequencies, begin to follow the type of session (and therefore frequency) you choose.

If you want to relax for example, the lights will gently pulsate at a frequency in the alpha range – as that is the frequency of a relaxed human brain. When stimulated as such, your brain begins to actually enter that mental state. The session types can be quite elaborate, including those for specific meditations, energizing, visualization, right or left hemisphere stimulation, sleep, or dazzling entertainment! That’s just to name a few.
