Q

what is the brain region responsible for sleep promoting?

A

Ventrolateral Preoptic Area (VPLO)

17
Q

What are the 4 brain regions responsible for wake promoting?

A
  • Locus Coeruleus (LC)
  • Raphe Nuclei
  • Tuberomammillary Nucleus (TMN)
  • Lateral hypothalamic area (LHA)
18
Q

Ventrolateral Preoptic Area
-Neurotransmitter
-SP or WP
-Associated sleep disorder

A

-GABA
-SP
-Insomnia

19
Q

Locus Coeruleus
-Neurotransmitter
-SP or WP
-Associated sleep disorder

A

-Norepinephrine
-WP
-Narcolepsy

20
Q

Raphe Nuclei
-Neurotransmitter
-SP or WP

A

-Serotonin
-WP

21
Q

Tuberomammillary Nucleus
-Neurotransmitter
-SP or WP

A

-Histamine
-WP

22
Q

Lateral Hypothalamic Area

23
Q

How does sleep deprivation impact adenosine in the day, and data wake and sleep intensity at night?

A

Increase adenosine and intensity

24
Q

How does napping impact adenosine in the day, and data wake and sleep intensity at night?

A

Decreases adenosine and intensity

25
Q

How does exercise impact adenosine in the day, and data wake and sleep intensity at night?

A

Increases adenosine and intensity

26
Q

What does adenosine bind to?

A

VPLO

27
Q

How does caffeine affect sleep?

A

-Acts as an antagonist to adenosine
-Prevents the binding of adenosine to its receptors
-delays sleepiness

28
Q

Zeitgebers

A

Environmental cues about time that reset brain time to 24 hours

29
Q

What are examples of zeitgebers?

A
  • Sunlight: when the sun sets it causes the release of melatonin
  • Exercise
30
Q

Clock genes

A
  • Set brain time to 24.2 hours
    -Without time cues we stay up later and later
31
Q

Thalamus Burst Mode

A

-Bursts of APs
-AAS off
-Promotes Sleep
-Synchronizes activity in cortex

32
Q

Thalamus Spike Mode

A

-Single APs
-AAS on
- promotes wake
-desynchronizes activity in the cortex

33
Q

What is the function of REM sleep and what is the consequences of disrupton

A
  • Alters memories so they are less emotionally distressing
  • disruption increases amygdala activity and emotional distress
34
Q

Examples of things that disrupt REM

A

Alcohol or cannabis
