module 16-19 Flashcards
What is a depressant?
Drug like barbituates, opiates, or alc that calm neural activity and slow body funtions
Whats the circadian rhythm?
The way our bodies synchornize with the 24-hour cycle of day and night. An internal biological clock
What is REM sleep?
When you are sleeping, the periods of fast eye movment, followed by energetic brain activity, most dreams happen
What is NREM sleep?
Non-rapid eye movement sleep, encompasses all sleep stages besides REM sleep. Waves in NREM1 are much smaller than waves in NREM3, there are three stages of NREM sleep
What are alpha waves?
The waves your brain gives off, can be seen on EEG. they are relatively slow brain waves of a relaxed, awake state
What is insomnia?
Persistant problems of either falling or staying asleep; results in tiredness and increased risk of depression
What is narcolepsy?
sudden attacks of overwhelming sleepiness, can be dangerous, for example falling alseep while driving
What is Sleep apnea?
Stop breathing repeatidly while sleeping; effects, fatigue+ depression (a result of slow-wave sleep deprivation)
What are night terrors? Who do they primarily effect?
Most common in children; appearing terrified, talking nonsense, or walking around during NREM3 sleep, different from nightmares
What is manifest content?
the symbolic, remebered story line of a dream
What is latent content?
the underlying and real meaning of the dream, not outright expressed
List everything about Alcohol:
Depressant, disinhibitor, slows sympathetic nervous system activity, supresses REM sleep, GABA
Barbituates:
tranqulizers, reduce anxiety, can be lethal, could cause overdose
Opiates:
Depress neural functioning, includes herion, codeine, morphine, methadone. When flooded with artifical opiate, brain stops producing endorphines
Stimulant:
excites neural activity, speeds up body functions. Includes; nitcotine, cocaine, meth, ecstacy
Cocaine:
Stimulant, supplies brain w/ dopamine, seratonin, and norepinephrine
Meth:
Reduces baseline dopamine levels after years of continual use; stimulant
Ecstacy:
Stimulant, mild hallucinagen; triggers dopamine release, releases stored seratonin and blocks its reuptake
hallucinagens:
Distort perceptions, evoke sensory images w out sensory input. (ex LSD, DMT, weed, molly)
What are post-hypontic suggestions
Help alleviate headaches, asthma, and stress-related anxiety and skin disordrers, done after hypnosis where patients can harness their own healing powers
As the night goes on dreams get—–, and the depth of sleep gets—–
longer, shallower
Give an example of a hypnagonic sensation….what stage of sleep do they occur in?
falling, floating, rotating; NREM1
In what stage do sleep talking and walking occur?
NREM3
Sleep paralysis happens in what stage?
REM
People who act out their dreams suffer from what disorder?
REM sleep behavior disorder
The activation synthesis theory of dreaming says that dreams are just the cortex making sense of random signals coming from the what?
Brainstem
After suffering trauma people commonly report?
Nightmares
What are NREM3 waves called?
Delta waves
Elderly people sleep:
many more cycles, less deep sleep, more waking up
Which theory of hypnosis involves dissociation?
divided conciousness theroy
Ernest Hilgred said there is a part of the hypnotized person that knows everything going on called the…
hidden observer
T or F: the social phenomenon theory or hypnosis says people are actively faking
false
Rapid bursts of brain activity that happen in stage 2 sleep
sleep spindles
Why is REM sleep called paradoxical?
the brain looks awake
