The EEG records the brain's electrical pulsations and these pulsations are shown on a monitor or printed out in peaks and troughs.

Beta is the most active brain wave pattern and indicates that the brain is actively engaged and alert. You emit beta waves when you are angry or afraid or performing activities that require concentration.

Alpha waves have a slower frequency and correspond to a relaxed state. Meditation produces alpha waves. Any time your mind drifts you are probably in the alpha state which also is an important part of dreaming.

Theta waves have a lower frequency than alpha and produce a deeper level of relaxation often associated with deeper states of meditation. This state can be filled with mental imagery because the mind is not engaged and is open, free and very relaxed.

Delta is the lowest brain wave with the slowest frequency. A deep, dreamless sleep is often associated with delta waves. This is the state our brains are in prior to going into REM sleep when we experience active dreaming.
