Brain Waves and Binaural Beats: A Gateway to Higher Consciousness, Enhanced Learning and Brain Function

I have to admit, I’ve always had a fascination with shortcuts to higher levels of consciousness and have shamelessly embraced technology to this end. A veteran in all manner of brain wave entrainment soundtracks, I’ve found some work better than others for increasing creativity, focus and learning; supporting meditation and calming an overactive mind, as well as promoting sound sleep.

For those who are new to brain synchronization technology, binaural beats are sound patterns that, when listened to through headphones, encourage synchronization of the left and right brain hemispheres. Depending on the speed of the binaural beats — gamma, beta, alpha, theta or delta brain waves are enhanced, each with their own beneficial characteristics. Production of brain chemicals — like DHEA, GABA, endorphins, serotonin, melatonin and growth hormone — is also triggered, while the stress hormone cortisol is lowered.

Ultimate Brain Power

To understand how binaural and brain synchronization works, we first have to look at the different levels of brain wave patterns, which fall into five categories:

Gamma: The fastest brain wave frequency, gamma brain waves measure between 25 and 100 Hz (cycles per minute) — with 40 Hz the most typical for humans. Peak concentration, exceptionally high levels of cognitive functioning and being in “the zone” are the most prominent characteristics of gamma brain waves. People with high levels tend to exhibit extraordinary intelligence and compassion, strong memory and incredible self-control. Seasoned meditators, like monks and nuns, often have elevated gamma brain wave activity. Compassion and loving-kindness practices appear to yield the highest level of gamma waves.

Beta: A rapid pattern that falls between 15Hz and 40Hz, beta is associated with alertness, arousal, cognition and concentration. Beta waves represent our normal waking consiousness and logic. At higher levels, beta waves can trigger stress, anxiety and restlessness. Most adults operate at the beta level throughout the day.

Alpha: Slower waves ranging from 9 to 14 Hz, this pattern is one of deep relaxation and the twilight state between sleep and waking. Alpha waves also encourage increased serotonin production. Meditation and access to the unconscious mind fall within the alpha realm. The higher end of alpha results in a relaxed, yet focused state with increased intuition.

Theta: Ranging between 5 and 8 Hz, dreaming (REM sleep), increased creativity, super-learning and heightened memory are all characteristic of theta waves. They also encourage the production ofcatecholamines, which are crucial for memory and learning. Trance, deep meditation, access to the unconscious mind and a feeling of deep spiritual connection all belong to theta.

Delta: The slowest frequency, delta waves fall below 4 Hz and are a pattern of deep, dreamless sleep with loss of body awareness. However, some research indicates that we may remain alert in a very deep trance-like, non-physical state. Our brains trigger large quantities of the healing growth hormone during the delta cycle. Access to the unconscious and collective unconscious mind happens during the delta state.

Benefits of Brain Wave Entrainment

Robert Monroe of the Monroe Institute found that using binaural beats to induce brain wave patterns resulted in “focusing of attention, suggestibility, problem solving, creativity, memory, and learning… sleep induction, pain control… and enhanced learning”. Other researchers have noted that slower brain wave patterns are accompanied by feelings of deep tranquility, flashes of creative insight, enhanced learning abilities and euphoria.
