What are Brainwaves?
Brainwaves are the actual rise and fall of the electrical impulses sent throughout the brain. The brain is made up of billions of neurons, each one constantly communicating with the others around it with electrical impulses. Because so many are firing at once the electrical activity actually forms waves or pulses of electrical activity which we call brainwaves. The different brainwave patterns can be recorded by electrical sensors placed on the head of an individual. The machine responsible for this type of recording is the EEG and through its use researchers have been able to map the different brainwave states and their relation to consciousness.

The Significance of Brainwaves
Since the invention of the EEG and the resulting research into the relationship between brainwaves and conscious state much information has been gathered. For example we now know that certain brainwave patterns relate to different states such as intense concentration, dreaming sleep, deep dreamless sleep, relaxation, contemplation, lucid dreaming and even exotic states of consciousness such as hypnosis, trance, visionary experiences or spiritual experiences.
The EEG has also been used to map the states of people with ADD, depression, anxiety and many other mental or emotional issues which makes it possible for doctors to get a good look at someone's emotional state simply by watching their brainwaves.
Brainwaves are effected by all of our senses and whatever a person is experiencing will effect their current brainwave state. With the use of any repetitious impulse to any one or more of our senses our brainwaves will naturally start to resonate with the given impulse. Flashing lights, watching a pendulum or hearing a constant rhythm will all stimulate the brainwaves of an individual to resonate with the rhythm of the sensory input. This is called Brainwave Entrainment.
Entrainment With Sound
With the use of certain sounds we can easily entrain a persons brainwaves to a certain frequency which corresponds to a certain mental state. As shown in the picture below a sound pulse will cause a cortical response in the brain of a listener at the same frequency as the sound wave.
As researchers have mapped many brainwave frequencies we can now use audio brainwave entrainment to easily induce any of the states that we desire such as, concentration, meditation, lucid dreaming, super learning, sleep and many others.
Brainwave Entrainment has over 70 years of solid research behind it. Click here to learn more
