suprachiasmatic nucleus
a pair of cell clusters in the hypothalamus that controls circadian rhythm
melatonin
a sleep-inducing hormone
EEG
a way of measuring sleep activity through brain waves
Hallucination/hypnagogic senstation
false sensory experiences
pineal gland
gland that adjusts the production of the sleep-inducing hormone melatonin
NREM sleep
non-rapid eye movement sleep
REM sleep
rapid eye movement sleep
memory restoration theory
that the function of sleep is to consolidate our memories
creative thinking theory
that the function of sleep is to feed creative thinking
recuperation theory
that the function of sleep is to help restore and repair brain tissue
sleep protects theory
that the function of sleep is to protect people and increase chances of survival
growth theory
that the function of sleep is to support growth
circadian rhythm
the biological clock; regular body rhythms that occur on a 24-hour cycle
beta wave
the brain waves of an alert, waking state
delta wave
the large, slow brain waves associated with deep sleep
alpha wave
the relatively slow brain waves of a relaxed, awake state
sleep paralysis
when during REM sleep your brain's motor cortex is active, but your brainstem blocks its messages
