(hypnic jerks/sleep/starts, dozing) (ex, on the bus) A k complex is a spike of activity when there"s a stimulus such as a noise or someone saying your name. Essentially your brain wakes you thinking its something that should be noticed. Eyes go in large slow full circles. (ex, napping) N3: (formerly stages 3 & 4): deepest most physically restorative stage of sleep. Muscle atonia (paralysis) (most people don"t move in their rem sleep) Dream recall is much better (excited to share your dream, for example) Paradoxical sleep eeg mimics wakefulness (which is why it is called paradoxical sleep) If there is something the body is supposed to do, there is a condition where the body wont do it. Parasomnias: anything that happens while you sleep ro is related to sleep. Insomnia: being unable to fall asleep or stay asleep.
