Understanding Brain Waves
We have one mind with two different functions: the conscious and the subconscious. These two functions move through four brain wave activities. They are Beta, Alpha, Theta, and Delta. Brain wave activity is said to be electrical energy produced by the brain and measured by (EEG) that monitors the electrical activity within the brain. Beta is the brain wave activity of the conscious function of the brain and is considered normal functioning of the brain. The brain wave activity is represented typically by 15 to 30 cycles per second as Alpha and Theta is the brain wave activity of the subconscious. Alpha brain wave activity generally is characterized by 8 to 14 cycles per second. Theta brain wave activity is represented typically by 4 to 7 cycles per second. Finally, Delta brain wave activity is generally described as less than four cycles per second. These are essential functions to understand in mental science.
In cognitive science, we train individuals to reach the alpha and theta state of consciousness to reeducate their subconscious. Hypnosis has taught us that our subconscious is very open to suggestibility in the alpha and theta states of consciousness. Alpha and Theta states of consciousness are referred to by hypnotists as altered states of consciousness and are manifest when you are under hypnosis. Cognitive science teaches how to reach these states of consciousness without hypnosis. Instead, it focuses on you clearing the mind of conscious thoughts.

These brain wave states of consciousness are also significant to our childhood. In that, from zero to seven, we are in a theta state of consciousness. Our childhood minds are wide open to taking everything in we hear and see. It is where our belief system starts to develop. Then from eight to thirteen, we are in an alpha state of consciousness. The alpha state of consciousness is not as powerful as the theta, but we are still very suggestible, and our belief system continues to build. As children, we take in the beliefs of our parents, siblings, relatives, peers, teachers, neighborhood, and culture, while these brain waves form our belief system. Finally, the age of thirteen is when we transfer into our beta state of consciousness.
