21
Q

Electroencephalogram (EEG):

A

Brain waves are studied by placing electrodes on the scalp
When neurons fire, they produce electrical activity (brainwaves)
Researchers can record electrical activity in response to certain stimuli or during different states of consciousness
Brainwave activity (measured with EEG) changes dramatically across the different stages of sleep

22
Q

Rapid-Eye movement (REM) Sleep

A

Eyes move rapidly under the eyelids
Brain waves appear similar to those during wakefulness
Dreaming

22
Q

Non Rapid-Eye movement (NREM) Sleep

A

distinguished by brain wave activity

23
Q

NREM Transitional Stage

A

Occurring between wakefulness and sleep
-Rates of respiration and heartbeat slow down
-Muscle tension decreases (relaxation)
-Core body temperature decrease (body cools off)
-“Light Sleep” (mostly alpha waves, easy to wake someone up)

24
Q

NREM Deep Relaxation Phase

A

Theta waves
-Sleep Spindles (rapid bursts of high frequency within the brainwaves)
-k-complexes (high amplitudes of brain activity)

25
Q

NREM 3: Slow-wave Sleep Pulse

A

-Respiration and heart rate slow down further
-“Deep Sleep” (delta waves, difficult to wake someone up)

26
Q

Dreams

A

Emotion regulation, crates new synapses in the brain (learning and memory)
-6 years of our lives are spent dreaming
-real-life worries, hopes, desires, known people and places

27
Q

Wish Fulfillment Theory

A

Freud
Dreams preserve our sanity by allowing us to gratify forbidden or unrealistic wishes
Dream content may be so threatening or disgusting that it was disguised in dreams

28
Q

Manifest Content

A

dream content

29
Q

latent content

A

dreams true meaning

30
Q

Information Process Theory

A

Rosalind Carter
dreams reflect life events that are important to us

31
Q

Activation Synthesis Hypothesis

A

Dreams are created because neuron waves are sent from the brain and then the cerebral cortex tries to make sense of it in pons

32
Q

Insomnia

A

difficulty falling or staying asleep

33
Q

sleep apnea

A

multiple bursts of not breathing

34
Q

narcolepsy

A

sudden slip into REM sleep

35
Q

night terrors

A

common in children; rare in adults
-extreme panic, fear, and screaming

36
Q

REM behavior disorder

A

mechanism that blocks the movement of the voluntary muscles fails
-results in kicking punching yelling while dreaming

37
Q

sleepwalking

A

eyes open, but still asleep

38
Q

Substance Use Disorder

A

pattern of drug use despite negative consequences

39
Q

physical dependence

A

need to take a drug to avoid changes in normal bodily functions and withdrawal symptoms

40
Q

Psychological Dependence

A

emotional need for a drug; thoughts about getting/using a drug

41
Q

Tolerance

A

Someone requires more and more of a certain drug to fell the effects

42
Q

Withdrawl

A

symptoms when drug use is stopped

43
Q

Stimulants

A

-increase neural activity
-reward and pleasure (highly addictive)
-caffeine, nicotine, cocaine

44
Q

Depressants

A

-suppress the CNS activity
-quiet the brain
-alchohol, anti-anxiety meds

45
Q

Opioids

A

-decrease pain
-highly addictive
-herion, morphine, fentanyl

46
Q

hallucinogens

A

-changes in experiences
-hallucinations
-LSD, ketamine, cannabis

47
Q

Hypnosis

A

extreme focus and attention where little attention is given to the external stimuli
-pain management, anxiety, depression
-in control of behaviors
-“stage of suggestibility”

48
Q

Disassociation Theory

A

one stream of mental activity occurs without awareness or control (somehow drive home without remembering)

49
Q

Social-Cognitive Theory

A

-people playing the role that is expected of them
-fulfilling social expectations

50
Q

Meditation

A

-increasers awareness and mindfulness
-relaxed state
-stress management, sleep, mood & anxiety disorders, pain management
