Narcolepsy
A disorder characterized by sudden and uncontrollable attacks of deep sleep, often brief, sometimes accompanied by paralysis and hallucinations
Hypnagogic
During Stage 1 sleep you may experience hypnagogic sensations-such as fantastic images (like hallucinations); feel like you are falling or floating weightlessly state between awake & falling asleep
People who claim to have been abducted by space aliens—often shortly after going to bed—commonly recall being floated off their beds. It is most likely that they have incorporated these sensations into their memories.
Selective attention
A teenager texting while crossing the street is not likely to notice a car rounding the corner and about to cross her path. This best illustrates the impact of selective attention
The focusing of conscious awareness on a particular stimulus
Circadian rhythm the biological clock; regular bodily rhythms (for example, of temperature and wakefulness) that occur on a 24-hour cycle.
Sleep Apnea a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings.
Most commonly associated with obesity
REM
rapid eye movement sleep, a recurring sleep stage during which vivid dreams commonly occur. Also known as paradoxical sleep, because the muscles are relaxed (except for minor twitches) but other body systems are active.
A recurring sleep stage during which most vivid dreams commonly occur
Alcohol consumption disrupts the processing of recent experiences into long-term memory by decreasing REM sleep
REM rebound the tendency for REM sleep to increase following REM sleep deprivation (created by repeated awakenings during REM sleep).
Change blindness
Failing to notice changes in the environment
NREM stages
Activity increases from stages 1-3
NREM-3: Sleepwalking is most likely to be associated with this stage ghrelin Sleep deprivation increases levels of this hunger-arousing hormone
