CONTINUUM
What are the two types of consciousness depicted on the continuum?
NWC and ASC
What does an EMG measure?
DARE activity of the bodies muscles.
What does brain wave amplitude refer to?
Height of brain waves
What is a stimulant?
drug that activates the CNS
Name a non-physiological method used to study sleep
sleep diary, video monitoring
Which is higher on the continuum: asleep or anaesthetised?
Asleep
What is the full name of an EEG?
Electroencephalograph
What does brain wave frequency refer to?
Number of waves per second or over time
what is a depressant?
Drug that inhibits the CNS
What is the equivalent BAC when comparing 24 hours of sleep deprivation?
0.10%
ability to distribute our attention and undertake two or more activities simultaneously
What does an EOG measure?
DAR electrical activity of the muscles surrounding the eyes.
What brain wave pattern would we expect to see in someone awake and alert?
Beta
What affect will a stimulant have on brain wave patterns?
More likely produce beta waves
What happens to the EMG reading of someone going from stage 1-4 sleep?
less electrical activity
How might emotional awareness differ between an ASC and NWC
ASC is likely to be distorted (dulled or heightened)
What are the 5 brain wave patterns recorded by an EEG?
Beta
Alpha
Theta
Delta
Beta-like
Which brain wave pattern indicates deep sleep?
Delta
What effect will a depressant have on brain wave patterns?
more likely alpha, theta, delta waves
How many hours of sleep should you get (adolescence)?
about 9 1/2 hours a night (not a week!)
the passage of time may not be judged accurately.
Why do we use the EOG in particular during sleep? (what can it indicate that the other devices might not be so obvious?)
REM sleep
Which brain wave pattern is a high frequency low amplitude wave?
Beta
Name a stimulant
caffeine, cocaine, nicotine etc
Melatonin
