---|---|
0) Beta waves | awake/alert…slows to… |
1) Alpha waves | rhythmic at times and transitions to... |
2) Theta waves | a little deeper sleep—undisturbed by minor noises |
3)Delta/Deep sleep | ½ brain waves = delta, ½ = theta |
4)Deeper sleep | more than 50% of brain waves are delta waves last (and deepest) of the sleep stages before REM sleep; stages reverse and then REM sleep begins |
REM STAGE | most vivid dreaming occurs, rapid eye movement, heart beats faster |
Activation Synthesis Theory | Neurons in the Pons fire RapidlyBrain tries to make sense of them by combining w/ existing knowledge & memory |
