Hemi-Sync® Technology

Hemi-Sync® research has been ongoing for over four decades, and today is concentrated in three distinct areas:

  • Clinical application by members of The Monroe Institute®'s Professional Division. This might involve, for example, studying Metamusic® as an aid for reducing anxiety in a dentist's waiting room.
  • Independent clinical or technical research by universities or other institutions on the mechanisms underlying the effectiveness of the Hemi-Sync® process. This research may be published in peer-reviewed journals and may include masters thesis and doctoral dissertations.
  • Applied research in The Monroe Institute laboratory to improve and expand Hemi-Sync® applications. The Institute uses conventional scientific procedures whenever feasible but does not limit itself to such processes.
