All of our thoughts, emotions and behaviors are rooted in the communication between neurons. Each of the millions of neurological synapses in our brain operate on electrical impulses which create an overall frequency. The frequency (wavelength) can be fast or slow, harmonious or discordant, but whatever it happens to be will affect our consciousness dramatically. Our brainwave state affects our ability to focus and many other important functions in our lives. Knowing how to identify your brainwave state is the first step in empowering you to consciously shift these patterns as needed throughout the day.
There are four brainwave states:
Delta brainwave activity (1-4 HZ or beats per second) is associated with deep sleep. This state is crucial for restoration of the body and healing. Delta has to do with the subconscious, the place where intuition arises.
Theta wave activity (4-8 HZ) reflects the dreamlike state between wakefulness and sleep. Theta rhythms are associated with meditation and shamanic states of consciousness. Theta increases creativity, enhances learning, reduces stress, and awakens intuition.
Alpha brain waves (8-12 HZ) are associated with relaxation, imagination, visualization and integrative modes of consciousness. This state of mind is considered a gateway to deeper realms of consciousness and is essential to well-being.
Beta brainwave activity (13-30 HZ) is associated with concentration, cognition, alertness, and focus. This state of consciousness allows you to make connections quickly and come up with solutions and ideas.
Consciously altering brainwave activity
People have meditated, used music, dance, and art for millennia to alter consciousness. Neuroscience research has demonstrated that certain external rhythms can cause entrainment of brainwaves. This idea has been applied with biofeedback, binaural beats, and other advanced forms of technology but it is basically rooted in the ancient rhythm of the shaman's drum. Indigenous shamanic cultures have been using rhythm to alter consciousness for thousands of years.
Rhythmic drumming induces altered states of consciousness, which have a wide range of therapeutic applications. A groundbreaking study by Barry Quinn, Ph.D., a clinical psychologist specializing in neuro-biofeedback therapy for stress management, demonstrated that even a brief drumming session can double alpha brain wave activity, dramatically reducing stress. The brain changes from Beta waves (focused concentration and activity) to Alpha waves (calm and relaxed), producing feelings of euphoria and well-being. This ease of induction contrasts significantly with the long periods of isolation and practice required by most meditative disciplines before inducing significant effects. Rhythmic stimulation is a simple yet effective technique for affecting states of mind.
The reason rhythm is such a powerful tool is that it permeates the entire brain. Vision for example is in one part of the brain, speech another, but drumming accesses the whole brain. The sound of drumming generates dynamic neuronal connections in all parts of the brain even where there is significant damage or impairment such as in Attention Deficit Disorder (ADD). According to Michael Thaut, director of Colorado State University's Center for Biomedical Research in Music, "Rhythmic cues can help retrain the brain after a stroke or other neurological impairment, as with Parkinson’s patients..." The more connections that can be made within the brain, the more integrated our experiences become.
