ACTUAL Questions and CORRECT
Answers
Stage W - CORRECT ANSWER waking state, which ranges from full alertness to the
early stages of drowsiness
Alpha Rhythm - CORRECT ANSWER most people with their eyes closed will have alpha
rhythm
Eye Movements - CORRECT ANSWER eye blinks at a frequency of 0.5-2 Hz are
common during wakefulness
drowsiness = blinking slows and may be replaced by slow eye movement
eyes open = rapid eye movements or reading eye movements may occur
EEG - CORRECT ANSWER when eyes are open, the EEG pattern is low-amplitude
activity with beta and alpha frequencies
EMG - CORRECT ANSWER high=amplitude muscle contractions and movement
artifacts are present
True or False: If an alpha rhythm isn't detectable on an EEG, stage W may still be scored if other
markers of alertness are present, such as eye blinks, reading eye movements, or irregular
conjugate eye movements - CORRECT ANSWER True
Stage N1 sleep - CORRECT ANSWER very first stage of sleep, characterized by low-
amplitude mixed frequency EEG activity, slow rolling eye movements, and the transition from
wakefulness to sleep
, often considered the lightest sleep stage where individuals can be easily awakened and may not
even perceive they were asleep
How is Stage N1 marked? - CORRECT ANSWER by the disappearance of alpha waves
and the onset of low-amplitude theta waves
N1 sleep: Transitional phase - CORRECT ANSWER represents the initial phase of sleep,
where the body begins to relax and brain activity slows down
N1 sleep: EEG characterisitics - CORRECT ANSWER primarily shows low-amplitude
mixed frequency activity with minimal slow wave activity and no prominent sleep spindles or K-
complexes
N1 sleep: eye movements - CORRECT ANSWER slow, rolling eye movements are
typically present
N1 sleep: awakening perception - CORRECT ANSWER people awakened form N1 sleep
often report feeling like they were not fully asleep
Stage N2 sleep - CORRECT ANSWER sleep characterized by the presence of K-
complexes or sleep spindles on an EEG, along with low-amplitude, mixed-frequency background
activity
N2 sleep: reeduced muscle activity - CORRECT ANSWER EMG activity is reduced from
stage N1 and wake
N2 sleep: no eye movements - CORRECT ANSWER EOG typically shows no eye
movements, but slow rolling eye movements my persist from stage N1
