The FOUR main BRAIN STATES as measured by EEG...

BETA, ALPHA, THETA and DELTA.
Each frequency has a characteristic blueprint-and produces a distinctive state of consciousness.

BETA waves (14 cycles per-second and above) dominate the normal waking state of consciousness when-attention is directed towards the outside world.

ALPHA waves (8-13 cycles-per second) are present during dreaming and light meditation when the eyes-are closed.

THETA waves (4-7 cycles per second) occur in sleep and are-dominate in the highest state of mediation.

DELTA waves (.5 to 3 cycles per second) are experienced in deep meditation and deep-sleep.
