Procedural Skills
The knowledge exercised in the accomplishment of a task
Circadian Rhythms
24hr Biological cycles. Mostly affected by light and darkness and are controlled by a small area in the middle of the brain
Melatonin
what regulates your circadian Rhythms
Physiological Pathway of the Biological clock
Specialized receptors at the back of your eye that are responsive to light ad those cells send signals to an area of the hypothalamus
Suprachiasmatic Nucleus
Stimulates the pineal gland
Melatonin Hormone
Promotes sleep, anything that interferes with the release of melatonin from the pineal gland is going to interfere with your circadian Rhythm
Awake
Beta Waves (low voltage, high frequency)
Drowsy
Alpha Waves prominent
Stage 1 Sleep
Theta Waves Prominent -could produce hallucinations
Stage 2 Sleep
Sleep spindles and mixed EEG activity
Stage 3& 4: Slow wave Sleep
progressively more delta waves
REM Sleep
Low voltage, high frequency
Cycle of sleep occurs
4-5 times a night. Each period of Rem getting longer each cycle.
Why do we sleep?
- To conserve energy
- adaptive because it reduces danger
- helps to restore energy and other bodily resources
Complete Sleep Deprivation
Would be when you’re not allowed to sleep at all
Partial Sleep Deprivation
Would be when you’re hours of sleep are reduced
What happens with Sleep Deprivation
- A lot of emotion
- Impairment in problem solving
- Impairment of attentional capacities
REM Rebound
