The brain is an electrochemical organ which is made up of billions of brain cells called neurons. These neurons use electricity to communicate with each other. The combination of millions of neurons sending signal at once produces an enormous amount of electric activity in the brain itself. Researchers have speculated that a fully functioning brain can generate as much as 10 watts of electrical power. If you had enough scalps hooked up, you might be able to light a flashlight bulb.

Each time a neuron fires, the electro-magnetic spark of energy that is released setting of a chain reaction among other neurons. The speed of the connection correlates to the speed of the frequency. Electrical activity of the brain is called brainwaves because of its cyclic, wave-like nature. The brainwaves pattern will change depending on what the person is doing. For example, the brainwaves pattern when we sleep are vastly different than the brainwaves when we wide awake. The brainwaves are measured in cycle per second or Herzt (Hz). There are four categories of brainwaves, ranging from the most activity to the least activity.


Beta Brainwave 12Hz-38Hz (Wide Awake)

Beta brainwave are associated with our waking activity. Beta brainwave are emitted when we are consciously alert or feel agitated, tense and afraid. Beta brainwave have low amplitude and are the fastest of the four different brainwaves. Beta waves are characteristic of a strongly engaged mind. A debater, or a teacher, or a host of talk show would all be in beta state when doing their work. Usually, this state in itself is uneventful but we should not understimate its importance. The lack of beta brainwave activity can cause mental or emotional disorders such as depression and insomnia. Stimulating beta brainwave can improve emotional stability, energy levels, attentiveness and concentration.

Alpha Brainwave 8Hz-12Hz (Relaxed)

Alpha brainwave can be found when we are awake but in a state of physical and mental relaxation. We still aware of what is happening around us. Light meditation and day dreaming are associated with alpha brainwave. You are also in alpha state when you get up in the morning and just before you sleep. Since Aapha brainwave is very receptive and absorbent mental state, you can use it to practice your creative visualization and auto suggestion technique. Its are also good for self hypnosis, mental reprogramming and accelerated learning.

Theta brainwave 3Hz-8Hz (Dream)

You will go to theta brainwave when you are in light sleep or extreme relaxation. It is a state of somnolence with reduced consciousness. Theta brainwave are associated with creativity, dreams and Extra-sensory perception for the student the theta state is something to learn to go at will. Theta brainwave are also be used for hypnosis and mental reprogramming.

Delta brainwave 0.2Hz-3Hz (Deep Sleep)

Delta brainwaveis the slowest band of brainwaves. Delta waves occur during deep sleep or catalepsy. You will loss your body awareness. During delta state, you do not dream and the brain is fully unconscious but it is important for the explorer of consciousness. Your body is healing itself and resetting its internal clocks in this state. Your human growth is also released.

The knowledge of brainwaves state will give you the ability to make use of specific characteristic of those states such as being intensely focused, relaxed, creative and restful sleep.

Although there are four different kind of brainwaves, but the truth is they are not really separate brainwaves. The categories are just for convenience. One brainwave state my predominate depending on the activity of the individual, but the remaining three brainwaves are still present in the mix of brainwaves at all times. So, we don't ever produce only one brainwave type at a time. As an example, while somebody is wide awake, he produce a high amount of beta brainwave. A component of alpha, theta and delta brainwaves are still exist with only at the trace level.
