25
What are delta waves? Large
slow brain waves associated with deep sleep
26
What are the sleep stages? A sequence of stages: awake
NREM-1
27
What happens when studying REM sleep? Using EEG
researchers observe rapid eye movements and saw-toothed brain waves
28
What physiological events occur during REM sleep? Heart rate rises
breathing becomes irregular
29
How does aging affect sleep? Sleep becomes more fragile with more frequent awakenings in older adults
30
What environmental factors affect sleep? Electric lighting
shift work
31
What is the role of the suprachiasmatic nucleus (SCN)? It controls circadian rhythm by adjusting melatonin production in response to light
modifying feelings of sleepiness
32
What happens to the SCN during the day? Light signals the SCN to suppress melatonin production
reducing sleepiness
33
What happens to the SCN at night? The SCN quiets down
allowing the pineal gland to release melatonin
34
What are the functions of sleep? Sleep serves protection
recuperation
35
How does sleep protect us? Sleeping at night helped our ancestors avoid dangers
leading to evolutionary sleep habits
36
How does sleep help in recuperation? It restores the immune system and brain tissue
providing resting neurons time to repair
37
How does sleep aid in restoration and rebuilding? Sleep consolidates memories by replaying recent learning and strengthening neural connections
38
How does sleep benefit creative thinking? Dreams have inspired great ideas
and sleep boosts insightful thinking and learning
39
How does sleep support growth? During slow-wave sleep
the pituitary gland releases growth hormone necessary for muscle development
40
What are the consequences of sleep loss? Sleep loss can lead to conflicts in relationships
depression
41
How does sleep loss affect physical health? Sleep deprivation suppresses immune cells
increasing the risk of viral infections and cancer
42
What are the cognitive effects of sleep loss? Decreased ability to focus
process memories
43
How does sleep loss affect the immune system? It reduces the production of immune cells
increasing the risk of viral infections
44
What effect does sleep loss have on fat cells? It increases fat cell production
leading to a greater risk of obesity
45
How does sleep loss affect the joints? It increases inflammation
which can lead to arthritis
46
What effect does sleep loss have on the heart? Sleep deprivation increases the risk of high blood pressure
47
How does sleep loss affect the stomach? It increases the production of ghrelin (hunger hormone) and decreases leptin (hunger-suppressing hormone)
48
How does sleep loss affect muscles? It reduces strength
slows reaction time
49
What is insomnia? A condition where individuals experience ongoing difficulty falling or staying asleep
leading to chronic tiredness
50
What is narcolepsy? A condition where individuals experience sudden attacks of overwhelming sleepiness
often leading to falling asleep at inappropriate times
51
What is sleep apnea? A disorder characterized by slopping breathing during sleep
leading to fatigue and depression
52
What is sleepwalking and sleeptalking? Conditions where individuals perform normal activities while asleep
common in young children
53
What are night terrors? Sudden
terrifying episodes that occur during NREM-3 sleep
54
What is Freud's theory of dreams? He believed that dreams satisfy unconscious wishes and that their manifest content is a symbolic representation of latent content
55
What is manifest content in Freud's dream theory? The remembered storyline of a dream
56
What is latent content in Freud's dream theory? The underlying meaning of a dream
57
What is the information-processing theory of dreams? It suggests that dreams help us sort out daily events and consolidate memories
58
What is the physiological function theory of dreams? It proposes that dreams serve a physiological function
providing the brain with stimulation during REM sleep
59
What is the activation-synthesis theory of dreams? It suggests that dreams are the brain's attempt to synthesize random neural activity during REM sleep
60
What is the cognitive development theory of dreams? It views dreams as part of brain maturation
overlapping with waking cognition and simulating reality
61
What is REM rebound? It is the tendency for REM sleep to increase following deprivation of REM sleep
62
What is a psychoactive drug? A chemical substance that alters perceptions and moods
63
What is substance abuse disorder? It is characterized by continued substance use despite significant disruption to life or physical risk
64
What is tolerance? The diminishing effect of a drug with regular use

impaired behavior control
66
What is withdrawal? The discomfort and distress experienced after discontinuing the use of an addictive drug
67
What are the major categories of psychoactive drugs? Depressants
stimulants
68
What are depressants? Drugs that reduce neural activity and slow body functions
such as alcohol
69
What is alcohol's effect on the brain? It disrupts the action of GABA and glutamate neurotransmitters
affecting memory and motor coordination
70
How does alcohol affect memory? It disrupts memory formation and suppresses REM sleep
which is necessary for memory consolidation
71
What are expectancy effects? The influence of others' expectations on an individual's self-perception and behavior
72
What are barbiturates? Drugs that depress the central nervous system
reducing anxiety but impairing memory and judgment
73
What are opiates? Opium and its derivatives
such as morphine and heroin
74
What is opiate addiction? Repeated use of opiates leads the brain to stop producing endorphins
resulting in withdrawal symptoms when opiates are removed
75
What are stimulants? Drugs that excite neural activity and speed up body functions
such as caffeine
76
What benefits do stimulants have? They increase alertness
aid weight loss
77
What is nicotine? A highly addictive psychoactive drug found in tobacco that stimulates the central nervous system
78
How does nicotine affect the brain? It reaches the brain within 7 seconds
increasing blood levels quickly
79
What is cocaine? A powerful and addictive stimulant derived from the coca plant that temporarily increases alertness and euphoria
80
How does cocaine affect neural transmission? It blocks the reuptake of dopamine
norepinephrine
81
What is methamphetamine? A highly addictive drug that stimulates the central nervous system
speeding up body functions and affecting energy and mood
82
What is the effect of methamphetamine on dopamine? It reduces baseline dopamine levels over time
83
What is Ecstasy (MDMA)? A synthetic drug that acts as a stimulant and mild hallucinogen
producing euphoria and social intimacy but with risks to mood and cognition
84
How does Ecstasy affect the body? It releases stored serotonin and blocks its reuptake
leading to dehydration
85
What are hallucinogens? Psychedelic drugs
such as LSD
86
What are hallucinations? Perceptions of sensory experiences that do not have an external source
87
What are near-death experiences? Altered states of consciousness following a close brush with death
