17
Q

About BRAC cycle

A

Sleep cycle
Cycle through about every 90 min

18
Q

Stages of sleep: Awake

A

Beta waves (15-30)

19
Q

Stages of sleep: Relaxed and drowsy

A

Alpha waves (8-12 cps)

20
Q

Stages of sleep: Stage 1

A

Light sleep
Lasts a few minutes
Theta waves (3.5-7.5 cps)

21
Q

Stages of sleep: Stage 2

A

Sleep spindles (burst of Braun activity, 1-2 sec) and K-complexs

22
Q

Stages of sleep: Stage 3

A

(0.5-2 cps)

23
Q

Stages of sleep: Stage 4

A

Delta waves are dominant

24
Q

Sleep stages 3 and 4 are called

A

“Slow-wave sleep”

25
Q

Sleep patterns

A

Stage 1 down to stage 4, then climb back up but REM instead of stage one, repeat but don’t dip down as far, REM gets longer as the night progresses

26
Q

REM brain activity

A

Regulated by brainstem
Limbic system activity increases
Areas near visual cortex active
Motor cortex active but signals blocked.
Decreased prefrontal activity

27
Q

Sleep - Restoration Model and evidence

A

Sleep recharges us from mental and physical fatigue

Sleep about 10min longer after exercise.
Adenosine (cell waste) may decrease alertness

28
Q

Sleep - Evolutionary/circadian model

A

Sleep is adaptive, increases survival
Mechanism for conserving energy

29
Q

Sleep disorder- Insomnia

A

Trouble falling/staying asleep
Most common sleep disorder

Causes are biological, psychological, environmental. Treatment includes stimuli control

30

Happens usually stage 3 or 4
Causes include stress, alcohol, hereditary, stress, meds
Psychotherapy and drugs can help treat

35
Q

3 theories of why we dream

A

Activation-Synthesis Theory - Brain tries to interpret (Synthesis) random brain activity (Activation)

Problem-Solving model- Helps us find solution to our problems

Cognitive-process dream theories - Dreams are just thoughts and come from the same part of the brain

36
Q

Four basic properties of consciousness

A

Intentionality (brain focuses on not too much at a time)
Unity (lots of info made into one consciousness)
Selectivity
Transience (the tendency to change)

37
Q

A

Low sensory awareness. Mind can input sensation and can output behavior

Rolling over in sleep when uncomfortable

38
Q

Full consciousness

A

Know and can report menta state

40
Q

Cognitive unconscious

A

All three mental processes that lead to a person’s thoughts and choices but aren’t experienced by the person
