How Hemi-Sync® Alters States of ConsciousnessTo understand how Hemi-Sync alters consciousness it is necessary to step back
from the limited concepts of binaural-beat entrainment. Two decades ago it was
assumed that prolonged exposure to binaural-beat stimuli influenced brain waves
to the point of altering ongoing EEG through entrainment of the
frequency-following response, a theorized process of nonlinear stochastic
resonance of brain waves with the frequency of the auditory stimulus. Since an
auditory frequency-following response could be measured at the cortex it seemed
logical to assume that the underlying mechanism must be some form of Newtonian
entrainment process at work. There is, however, no effect-mechanism to support
the notion that entrainment of the frequency-following response is responsible
for alterations in consciousness. We now know that the EEG signal strength of
the measured auditory frequency-following response is extremely low. At this
point it is hard to even speculate that it could in some electromagnetic
inductive way alter prevalent ongoing brainwave activity. On the other hand,
demonstrating the mere presence of a frequency-following response to the
binaural beats of the Hemi-Sync process using evoked-potential EEG protocols
provides some evidence of the neurological impact of this stimulus. Hemi-Sync influences consciousness by providing information to the brain's
reticular activating system (RAS). The word reticular means "net-like"
and the neural reticular formation itself is a large, net-like diffuse area of
the brainstem. The RAS controls arousal, attention, and awareness - the elements
of consciousness itself. How we interpret, respond, and react to information
(internal stimuli, feelings, attitudes, and beliefs as well as external sensory
stimuli) is managed by the brain's reticular formation stimulating the thalamus
and cortex, and controlling attentiveness and level of arousal. Listening to Hemi-Sync provides information to the RAS because the unique Hemi-Sync binaural-beat wave form is accepted as a brainwave pattern by the reticular formation. This information encompasses the character, quality, and traits of the state of consciousness that the Hemi-Sync pattern represents. If internal stimuli, feelings, attitudes, beliefs, and external sensory stimuli are not in conflict with this information, the RAS will alter states of consciousness to match the Hemi-Sync stimulus as a natural function of maintaining homeostasis. The brain automatically and actively regulates all body functions to maintain homeostasis - an internal equilibrium. In a natural and constant attempt to maintain homeostasis the RAS actively monitors and continues the cortical replication of ongoing brainwave states (unless, of course, there is reason to make an adjustment due to new information from internal sources or external sensory input). However, because of the natural brainwave-like characteristics and persistence of the Hemi-Sync sound field, the RAS initiates cortical replication of the Hemi-Sync stimulus, believing the Hemi-Sync pattern to be the ongoing brainwave state. As time passes, the RAS monitors both the internal and external environment and the state of consciousness itself to determine, from moment to moment, its suitability for dealing with existing conditions. As long as no conflicts develop, the RAS naturally continues aligning the character, quality, and traits of consciousness with the information in the brainwave-like pattern of the Hemi-Sync sound.
