Psychology. New York: Worth Publishers, 1995: 115. "Brain waves have been grouped according to their frequencies and labeled with Greek letters. Their most common frequencies include alpha, beta, delta, and theta."
alpha 8 - 12 Hz
beta > 13 Hz
delta 3 Hz
theta 4 - 7 Hz
"The Brain & the Mind." Psychology Volume 1. 2002: 117. "Delta waves occur mainly in infants, sleeping adults or adults with brain tumors. Theta waves occur mainly in children ages 2 - 5 years old. Alpha waves occur in adults who have their eyes closed or who are relaxed. Beta waves mainly occur in adults who are awake, alert or focused."
alpha 8 - 13 Hz
beta 13 Hz
delta 1 - 3 Hz
theta 4 - 7 Hz
"The Brain & the Mind." Psychology Volume 2. 2002: 97. "Hans Berger made many discoveries from the EEG recording and he found that the brain oscillate at about 10 cycles per second when the eyes are closed and relaxed and he called them alpha waves."
alpha 10 Hz
Webster's Third New International Dictionary. Merriam Company, 1981: 909. "Rhythmic fluctuations of voltage between parts of the brain resulting in the flow of an electric current, that has a pulsation frequency of 10 or more per second." > 10 Hz

State Frequency range State of mind
Delta 0.5Hz - 4Hz Deep sleep
Theta 4Hz - 8Hz Drowsiness (also first stage of sleep)
Alpha 8Hz - 14Hz Relaxed but alert
Beta 14Hz - 30Hz Highly alert and focused
alpha 0.5 - 4 Hz
beta 14 - 30 Hz
delta 0.5 - 4 Hz
theta 4 - 8 Hz
Ever wonder what's going on up there in your brain at different states? Ever ponder about the brain wave frequencies when you're asleep, tired, relaxed, or energetic? Well, brain wave frequencies are categorized in 4 states: alpha, beta, delta, and theta.
* Alpha waves occur when a person is relaxed, but alert, having a frequency of 8 - 13 Hz. During this state, a person is awake but resting. During sleep, alpha waves are replaced by beta waves.
* The state of being focused, alert, or engaged in any form of activity are related to beta waves and they have a frequency of 14 - 30 Hz.
* After a really long day, all a person desires is to fall into a deep sleep. Delta waves are associated with deep sleep. Their frequencies range from 0.5 - 4 Hz. Delta waves are known for triggering the release of growth hormone, which provides healing, hence the reason why sleep is so important during the healing process.
* Theta waves have a frequency of 4 - 8 Hz and they occur mainly in children during the early stages of sleep, or in adults when they are emotionally stressed.

Choosing Programs that are Right for You

Brain States
Going deeper into relaxation, you enter the elusive and mysterious Theta state where brain activity slows almost to the point of sleep, but not quite. Theta is the brain state where magic happens in the crucible of your own neurological activity. Theta brings forward heightened receptivity, flashes of dreamlike imagery, inspiration, and your long-forgotten memories. Theta can bring you deep states of meditation. A sensation of "floating." And, because it is an expansive state, in Theta, you may feel your mind expand beyond the boundaries of your body.

Theta rests directly on the threshold of your subconscious. In biofeedback, it is most commonly associated with the deepest levels of meditation. Theta also plays an important part in behavior modification programs and has been used in the treatment of drug and alcohol addiction. Finally, Theta is an ideal state for super-learning, re-programming your mind, dream recall, and self-hypnosis.
Theta waves range between 4-7 HZ. Theta is one of the more elusive and extraordinary realms we can explore. It is also known as the twilight state which we normally only experience fleetingly as we rise up out of the depths of delta upon waking, or drifting off to sleep. In Theta, we are in a waking dream, vivid imagery flashes before the mind's eye and we are receptive to information beyond our normal conscious awareness. Theta has also been identified as the gateway to learning and memory. Theta meditation increases creativity, enhances learning, reduces stress and awakens intuition and other extrasensory perception skills.
To enter the Theta state try Deep Meditation, Sacred Ground, Guided Meditation, Deep Learning, or Deep Insight.

to be more precise, physical and other Healing happens, in Delta Wave states(deep sleep) or in states oscillating between THeta and Delta.. SPIRITUAL MAGIC happens in Theta mainly...sleep. deep sleep.
