Awareness of the outside world and yourself
Circadian rhythm
“sleep/wake cycle” Operates on a 24-24 hour cycle and is controlled by the suprachiasmatic nucleus within the hypothalamus
What are the 2 main things sleep does?
1) protein creation and body repair throughout the body
2) Maintaining plasticity to consolidate info and integrate it with your stored memories
Awake is what type of waves
Beta waves
Relaxed is what type of waves
Alpha waves (the waves are slower)
Non-REM 1
Hypnotic, aware of stimuli, hallucination, jerks
Non-REM 2
Sleep spindles & K complexes, your brain slows
Non-REM 3
Deep sleep (delta waves)
- sleepwalking & talking
- night terrors
- breathing & heart rate ↓
