22
Q

amplitdues

A

height of waves

23
Q

regularity

A

how consistent/erratic waves appear

24
Q

beta waves

A

irregular, mostly low amplitude, desynchronized and erratic

25
Q

descynchrony

A

reflects fact that many different neural circuits are actively processing info

26
Q

alpha activity

A

when individual awake, but relaxed; waves look more regular and predictable at 8-12 Hz

27
Q

theta activity

A

3.5-7.5 Hz

28
Q

Sleep spindles

A

brief bursts of activity that occur 2-5 times a minute during sleep stages 1-4

29
Q

K-complexes

A

during sleep stage 2 once a minute; triggered by unexpected noises

30
Q

Slow-Wave Sleep

A

stage 3, firing across cortex is coordinated

31
Q

delta

A

slow, regular, high-amplitude waves

32
Q

REM

A

rapid eye movement; eyes move side to side beneath closed eyelids; when we have vivid, narrative-based dreams

33
Q

Hypnogram

A

graph of sleep stages

34
Q

rebound phenomenon

A

When brain deprived of REM, brain tries to enter REM more quickly and spends proportionally more time in REM than SWS; suggest there is a need for a certain amount of REM

35
Q

evolutionary hypothesis of dreams

A

Revonsu (2000) we often dream about survival and can lead to enhanced performance when encountering threats; emotional content matches personal emotional problems

36
Q

Psychoactive drugs

A

influence mood, thoughts, behaviour; chemical composition of brain altered

37
Q

drug tolerance

A

larger and larger dose is required to achieve same physical and psychological effects

38
Q

dependence

A

physical/psychological need for drug for normal functioning

39
Q

withdrawal

A

headaches, shaking, vomiting, changes in mood

40
Q

Depressants

A

slow or depress arousal of central nervous system

41
Q

alcohol

A

relaxation, drowsiness, improved mood, increased self-confidence; increased consumption - impaired judgement, slowed reaction times, uncoordinated motor movements (INHIBITS GLUTAMATE AND INCREASES GABA AND DOPAMINE)

42
Q

Glutamate

A

alcohol inhibits effectiveness of this excitatory neurotransmitter for learning and memory

43
Q

GABA

A

main neurotransmitters for relaxed states

44
Q

barbiturates & benzodiasepine

A

used to treat anxiety, OCD, and epilepsy; create subjective sense of relaxation; barbiturates quite addictive (INCREASES GABA)

45
Q

stimulants

A

increase activity of nervous system

46
Q

caffeine

A

blocks inhibitory neurotransmitter adenosine, may increase amount of excitatory neurotransmitters

47
Q

nicotine

A

highly addictive, stimulates release of acetylcholine (excitatory); may increase activity related to cognition; absorption of the lungs = rapid effects (STIMULATES/IMITATES ACETYLCHOLINE AND INCREASES DOPAMINE)

48
Q

cocaine

A

prevents reuptake of dopamine

49
Q

hallucinogens/ psychedelic drugs

A

synesthesia

50
Q

LSD

A

alters emotions and being in a “waking dream”; (agonist of serotonin)

51
Q

mescaline

A

colour perception feels enhanced, repeating patters in visual field, feel out of body; numbness, tension, anxiety, intense nausea

52
Q

psychoactive drugs

A

alter behaviour and awareness by exploiting naturally occurring brain system

53
Q

amphetamines

A

inhibit reuptake and stimulate release of dopamine
