Fatigue and Sleep Flashcards
In the transitional stage, where is it we see increases or decreases in alpha?
Centrofrontal
Temporal
Where is it we see increases in slow activities during transitional stage? i.e. delta/theta
Posterior (inc. alpha)
Centrofrontal (inc. alpha)
Temporal
Frontocentral dominant beta. What stage?
transitional to post-transitional
Main feature of transitional to posttransitional
generalised slowing of 3-5Hz activity
In stage 2. where is it we see demonant theta?
midtemporal
In transitional which brain part don’t we see alpha increases in?
temporal.
Where is slowing in stage three?
Posterior and frontocentral
Stage 2 shows slowing here:
Stage 3 shows slowing here:
2: generalised
3: frontocentral, posterior
How long does chronic fatigue have to last to fit the definition>
> 1 month
where in the hypothalamus can talk to the pineal gland?
SUPRACHIASMIC NUCLEUS
What neurotransmitters are mainly used in the structures involved in sleep?
Mainly ACh and 5-HT
What structures are involved in sleep?
pons, medulla, thalamus, hypothalamus, limbic system
What does ARAS stand for?
Ascending Reticular Activating System
What sleep stage do we see spindles and K-complexes?
Stage 2
Describe stage W
alpha.
Describe stage classical 3
20-50% delta, high amplitude
Describe stae 4
50% delta
In what stage is theta dominant?
Stage 1
Describe learning in sleep on an EEG
associated with fast-wave or alpha actvity.
Can we learn during sleep?
No. Only very limited, simple repetitive sounds or words with no complexity can attain meaning in the waking state.
What’s teh difference between day sleeping and night sleeping?
Day sleeping reaches REM EARLIER and reaches STAGES 1 AND 2 LATER.
Who are better at day sleeping as a thing: nurses or night security guards?
Guards. Night work can show better adjustment to rhythm than rotating shift work.
BAD FOR NURSES, BAD FOR PATIENTS
What stage of sleep do we see repetitive limb movement?
N1 to N2
80% of people with _____ have repetitive limb movement disorder.
Restless leg syndrome.
