Accessing Anomalous States of Consciousness with a Binaural Beat Technology

by F. Holmes Atwater

Abstract — Exposure to binaural beats in an environment of restricted stimulation coupled with a guidance process can safely provide access to and experiences in many propitious states of consciousness. This method requires a unique combination of well-understood psycho-physiological inductive techniques with the addition of a refined binaural-beat technology. Binaural beats provide potential consciousness-altering information to the brain’s reticular activating system. The reticular activating system, in turn, interprets and reacts to this information by stimulating the thalamus and cortex thereby altering arousal states, attentional focus, and the level of awareness, i.e., the elements of consciousness itself. This effective binaural-beat process offers a wide variety of beneficial applications and vehicle for the exploration of expanded states of consciousness.

Becoming Our Own Guinea Pigs

by Joseph M. Felser, Ph.D


What is the source of philosophical thought? Why do we ask fundamental questions about human existence? Early philosophers like Socrates, whose ideas and practices were shamanistic, believed that rational thinking was rooted in and fed by non-rational experiences, such as visions, dreams, trances, ecstasies, mystical encounters, and other experiences of wonder that excite our curiosity and imagination. But modern Western philosophy largely rejected this older view, holding instead that genuine philosophical analysis can only arise through the purging of all such “extra-rational” influences that interfere with our use of reason, logic, and observation via the physical senses. This paper outlines a new research project, to be undertaken by the author in concert with The Monroe Institute®, that is designed to explore the question of how experiences of “wonder” relate to processes of philosophical-type thinking, and in particular how this question is addressed by TMI program participants.

Behavioral Effects of Hemi-Sync® Embedded Meditation Music on a Horse

The study reported here asked whether discernible behavioral differences could be detected in a horse listening to meditation music compared with listening to the same meditation music embedded with Hemi-Sync.

Binaural Auditory Beats Affect Vigilance Performance & Mood

by James D. Lane, Stefan J. Kasian, Justine E. Owens, and Gail R. Marsh

This study compared the effects of binaural auditory beats in the EEG beta and EEG theta/delta frequency ranges on mood and on performance of a vigilance task to investigate their effects on subjective and objective measures of arousal. 

Binaural Beats and the Regulation of Arousal Levels

by F. Holmes Atwater, BA


This paper describes two studies. A first study measured the neural accommodation (changes in ongoing or overall brain-wave activity) associated with complex binaural-beat stimuli. A second study, based on the same protocol, measured changes in ongoing brain-wave activity associated with placebo stimuli.

EEG and Subjective Correlates of Alpha-Frequency Binaural-Beat Stimulation Combined with Alpha Biofeedback

by Dale S. Foster

The purpose of this study was to determine the effects of alpha-frequency binaural-beat stimulation combined with alpha biofeedback on alpha-frequency brain-wave production and subjective experience of mental and physical relaxation.

Effects of Binaural-Beat Stimulation on Recovery Following Traumatic Brain Injury: A Pilot Study

by Signe Klepp, OT


Patients suffering from traumatic brain injury (TBI) lose the ability to structure their own life. Rehabilitation is expensive in time, money, and effort. A noninvasive, patient-controlled method, binaural-beat auditory stimulation, may elicit changes in states of consciousness and mood. This study assesses the feasibility and efficacy of using this method to improve self-esteem, quality of life, and function of daily living for persons suffering from old TBI.

Effects of Long-Term Participation in the Monroe Institute Programs-Phases 1 and 2

by Cam Danielson

The Monroe Institute (TMI), through its patented sound technology, has demonstrated changes in focused states of consciousness for thousands of individuals over the last 30 years. While ongoing research at the Institute on the nature of different states of consciousness is yielding rich insights into human development, a continuing challenge for the leadership of TMI is to understand how repeated exposure to Hemi- Sync® technology in controlled workshop environments affects the quality of individual lives.

Effects of Music and Hemi-Sync® on a Child with a Seizure Disorder

by Suzanne Evans Morris, Ph.D.

Since Suzanne's initial experience with Hemi-Sync, she has been fascinated by the potential of the Hemi-Sync signal to assist the damaged brain in achieving a greater state of balance and organization.

Energy Medicine and the Unifying Concept of Information

by Beverly Rubik, Ph.D.

Certain types of alternative medicine that involve subtle or very low intensity nonmaterial stimuli are popularly known as energy medicine. Examples are healer interventions, homeopathy, electromagnetic (EM) therapies, and possibly acupuncture. Although clinical and fundamental research on these modalities exists, they remain outside the mainstream because they challenge the dominant biomedical paradigm by defying conventional scientific explanation.

Hemi-Sync® into Creativity

by Chok C. Hiew, Ph.D.

This paper reports a pilot study designed to test the impact of Hemi-Sync audiotapes on creative responses and divergent thinking. Two Hemi-Sync tapes were used. In Session I, the Deep 10 Relaxation tape was used to induce a deep state of physical and mental relaxation. In Session II, after repeating the Deep 10 tape for the first 6.5 minutes, subjects spent the remainder of the session listening to the Surf tape. Surf consists of the sounds of ocean waves and Hemi-Sync with no verbal instructions. It was predicted that after listening to this Hemi-Sync tape in Session II, subjects would show the best performance when evaluated for creativity.
