rapid eye movement
-story like dreams

Question 23

what are the functions of sleep?

Answer 23

-protection (protects our health)
-recuperation (repair of brain tissue)
-restoration (strengthens and consolidates memories)
-production (allows you to be more creative)
-growth (allows pituitary glands to secrete growth hormones; increases energy)

Question 24

Answer 25

since people are not getting enough sleep the night of daylight savings

Question 26

Answer 26

-both sleep problems -night terrors: stage 4 disruption, typically affects children, wont remember next day (big delta waves) nightmares: happens in REM (stage 5), happens in any age, (alpha beta waves)

Question 27

rem sleep behavior disorder (RBD)

Answer 27

-lack of sleep paralysis (you are supposed to be a little paralyzied during sleep) -people can get up and act out their dreams

Question 28

narcolepsy

Answer 28

-cataplexy (muscles won't move) -sleepiness -sleep paralysis

Question 29

sleep apnea

Answer 29

obstructive- something blocking airway central: something in brain thats blocking breathing signals in sleep

Question 30

insomnia

Answer 30

-hard time falling asleep -waking up at 2 or 3 in the morning early- hard time falling asleep middle-wake up in middle of night but goes back to sleep late- wake up really early and can't go back to sleep

depressants: alcohol- psychological effects

Answer 39

-memory disruption -reduced self awareness and self control -expectancy effects

Question 40

barbiturates & opiates

Answer 40

barbiturates tranquilizers -reduce anxiety &/or induce sleep -impair memory -combines with alcohol is lethal opiates -depress neural activity -lessen pain & anxiety

Question 41

cocaine

Answer 41

increases activity of dopamine, norepinephrine and serotonin ----gives a rush -then depletes these NTs -----crash -increases aggression -cardiac issues

Question 42

stimulants

Answer 42
