These last about a day and include sleep/wake and other biological processes that adjust to light/dark.
What is circadian cycles?
100
This is where the circadian clock is in the brain.
What is the suprachiasmatic nuclei?
100
This part of the hypothalamus promotes sleep.
What is anterior hypothalamus?
100
This is the brain area associated with REM.
What is caudal brain stem nuclei?
100
This is a disorder of initiating and maintaining sleep, associated with disturbances of function.
What is insomnia?
200
This is produced by the pineal gland and is the hormone of darkness.
What is melatonin?
200
These are the waves on the EEG during wakefulness.
What is alpha and beta waves?
200
This is the theory that states that during REM, brainstem circuits are active and communicate with the cortex. A dream is our brain's attempt to make sense ofthe random stuff.
What is activation-synthesis theory of dreaming?
200
This type of sleep is restorative.
What is slow wave sleep?
300
This is the mechanism we have inside of us that regulates sleep.
What is circadian clock?
300
This is when you move back in time, or go from east to west in travel.
What is phase delay?
300
This sleep stage includes k complexes and sleep spindles.
What is Stage 2?
300
These theories think that being awake disrupts homeostasis and sleep is necessary to restore it.
What is recuperation theories?
300
This is a kind of REM sleep where you act out your dreams.
What is REM sleep without core muscle atonia?
400
This is alignment of ones' circadian rhythm to external stimuli.
What is entrainment?
400
This structure allows light information to contribute to circadian rhythms
What is retinohypothalamic tracts?
400
This is how long the sleep cycle is.
What is 90 minutes?
400
Explain Dement and Wolperts study on incorporating outside information into dreams.
What is sprayed water on sleeping Ps in REM and woke them out, 14/33 reported water in dreams.
400
This a therapy for insomnia that changes the amount of time you have in bed.
What is sleep restriction therapy?
500
Explain free running rhythms.
What is circadian rhythms that are not learned but occur naturally. Vary from P to P but usually around 25 hours.
500
Explain "Clock-Blind" mice study.
Used mutant mice without RHT. Established zeitbergers and light patterns in normal mice. Then did same with mutant ones. Mutant ones showed free running rhythms no matter what. Thus, RHT necessary for light entrainment.
500
This area between the interior and superior colliculi deals with continuous slow wave sleep in EEG.
What is Cerveau Isole?
500
Name the characteristics of REM sleep.
What is loss of core-muscle ton, low amplitude, high frequency EEG, cerebral activity at waking level, increase in ANS activity, muscle twitching, erection?
500
Explain carousel apparatus study.
2 rats were placed in separate chambers, EEG of experimental. Rat is dunked into water if falls asleep. Experimental rat dies within days, control lives. Could be sleep deprivation or stress/physical damage.
