Now these brain wave patterns can be placed into groups according to the frequency range which is directly related to the state of mind of the person. These are …
Beta
(13 Hz - 30 Hz) is the state of normal, wakeful consciousness. As you
are working, driving, talking, etc., you are usually in Beta. High beta
activity is
sometimes associated with anxiety, panic and stress.
Alpha (8 Hz - 12 Hz) is a state of light relaxation. Typified by a calm, focused mind. Alpha is sometimes called the "super learning state" because the brain seems to be more receptive and open to new information. Most people who meditate, do so in alpha.
Theta (4 Hz - 7 Hz) is a state of deep relaxation. Dreams and deep, meditation are often associated with theta.
Delta, (0.5 Hz - 3 Hz) the slowest of the brainwave patterns, can be a state of deep sleep, or trance-like consciousness. Maintaining awareness in delta has been known to open a path to the unconscious."
