, is an in-home audio training program designed to guide users into expanded states of consciousness. Developed by Robert Monroe Monroe Institute , the series uses a proprietary sound technology called : By entraining the brain to specific frequencies,
: The exercises guide listeners through numbered "Focus" states, such as ("mind awake, body asleep") and (the "no time" state). Resonant Tuning Developed by Robert Monroe Monroe Institute , the
Hemi-Sync Gateway Tapes , officially known as The Gateway Experience
to influence brainwaves. When a user wears stereo headphones, each ear receives a slightly different frequency; the brain perceives a third "beat" frequency that matches the difference between the two. Hemispheric Synchronization
(hemispheric synchronization) to balance the left and right sides of the brain. CIA (.gov) How the Technology Works The tapes utilize binaural beats
