Brain Entrainment
Brainwaves are the waves of electrical activity within the brain that are always present and change continually. They change with our moods, our surroundings and with our physical activity. Research shows that certain types of brainwaves are prevalent during specific activities.
For example, during high energy activities predominate brainwaves would be Beta. That is not to say the other brain waves will not be present, only that the Beta activity would be more pronounced. Other activities will show Alfa, Theta and Delta waves being more predominate. Since the discovery of brainwaves and the equipment used to read brainwaves, we have been able to document which brainwaves are predominate during certain activities. Knowing how the brain is reacting during these activities makes it possible to duplicate these patterns and “teach” the brain to revert to these patterns using music embedded with binaural beats. Hence, the term “Brainwave Entrainment”. This has proven to be a valuable activity in learning to relax, heighten your creativity, and enhance your focus for problem solving and many other brain states.
The application of the binaural brainwave entrainment process is quite simple. While listening to music using headphones, you hear two pure tones, one in each ear. Let's say 500 Hertz and 510 Hertz. Each ear hears a singular tone. Your brain detects the difference between these two frequencies and produces a 3rd tone of 10 Hertz inside the brain.
Even though you perceive this 10 Hz sound, the third tone is not an actual sound at all; it is in fact an electrical signal that is created as your brain processes each tone from the left and right ear separately. As the brain continually processes this 3rd ghost signal, it begins to emulate (or “entrain”) to that 10 Hz stimulus. This phantom 10 Hz signal is created by both sides of the brain working in unison. This dual processing can lead to a state called hemispheric synchronization, or whole brain sync. This high function brain state occurs when both sides of the brain are functioning in tandem.
As you can see below, each one of the four brainwaves actually has its own electrical activity measured in Hz. In the example above the phantom 10Hz signal would result in causing your brain to sync with the “Alfa” brainwave state, resulting in increases of the characteristics of “Alfa” brain activity. Through simply listening to music with the binaural beat your brain will “entrain” itself to this 10Hz activity.
Beta: 13 - 25 Hz
* This brainwave is the predominant frequency when we are fully awake and alert
* Active awareness directed to the outer world
* These brainwaves are present with stress, paranoia, worry, fear, and anxiety
* Also present with hunger, depression, irritability, and moodiness
* Insomnia is the result of producing excessive beta brainwaves
* Associated with excessive "mental chatter" and self-destructive impulses
* Too much time in the beta state weakens the immune system
* Our conscious mind
Alpha: 8 - 12 Hz
* This alpha state is where meditation and relaxation begins
* We start to encounter the wealth of effortless creativity flowing just beneath our conscious state
* Awake but deeply relaxed
* Studies have shown the alpha state has been associated with "peak performance" where elite athletes produce alpha brainwaves prior to concentrated performance (shooting a free throw, hitting an important golf shot). Lower level athletes' brains produce anxious beta brainwaves
* In the alpha state we learn, process, memorize and recollect large sums of information fast with peak effectiveness
* Highly creative people have been shown to have "bursts" of alpha brainwaves when they have good ideas
* Alpha brainwaves are thought to make the brain "act young" again
* In the alpha state fears, habits, and phobias begin to melt away
* Alpha brainwaves bring an effortless sense of comfort, peace, and harmony
* Best for "super learning"
* The alpha state is the first layer of our subconscious mind
* A gateway to deeper states of awareness
Theta 4 - 7 Hz
* Theta brainwaves become prominent when we go deeper into meditation and relaxation. Almost trance-like
* Here, brain activity decelerates to the threshold of the sleep stage
* One of the more indescribable and wonderful realms we can explore
* The theta state produces flashes of creative visualization through vivid imagery
* In this state we feel much more open and connected to other people
* People often report a feeling of floating while producing theta brainwaves
* Theta brainwaves are thought to bring out a person's dormant extrasensory perception (ESP) skills
* The theta state heightens problem solving skills
* Having dominant theta brainwaves are correlated with insight and intuition
* Theta brainwaves bring inspired thought and increased motivation
* Sometimes long-forgotten memories come to the surface
* Children have strong theta brainwaves, which helps to explain their superior ability to learn
* Theta is briefly experienced as we climb out of the depths of delta upon waking, or falling asleep
* The theta state is the deeper sub-conscious to super- conscious part of the mind
Delta: 1 - 3 Hz
* The delta state is associated with "no thinking" during deep, dreamless sleep
* Although a difficult state to entrain, delta brainwaves are very rewarding
* Delta is said to be the entrance to non-physical states of reality
* A crucial state for renewal, healing, and rejuvenation
* The immune system strengthens in the delta state
* The delta state is the unconscious/super-conscious part of our mind
Brainwave entrainment has proven to be a safe and harmless way to relieve a variety of symptoms. It is now used in hospitals and clinics around the world. Through recent technology, nexNeuro is able to bring a simple and easy to use EEG headset for use in brainwave entrainment in your home or office. nexNeuro has employed an expert in music and binaural beat to assure the effectiveness of our program.
