The scoring of stage N3 sleep requires which of the following:I: 20% or more of the epoch consisting of activity of 2 Hz or slower wave frequencies which measure greater than 75 μV in amplitudeII: 75% high voltage theta activityIII: absence of sleep spindles and K-complexes

According to the scoring rules prior to the new AASM Scoring Manual, what stage of sleep is this epoch?

According to the AASM Scoring Manual, spindles can be scored as arousals:

What are the recommended derivations for EEG placement according to the AASM Scoring Manual?

The following are hallmarks of stage I sleep except:

According to the AASM Scoring Manual, the recommended electrode impedances for EEG should not exceed:

Arousals cannot be scored:

A burst of 12-14 Hz EEG activity, lasting at least 0.5 seconds are:

Which of these is the best definition of an EEG arousal during NREM sleep?

5.1 A = [ANS1] B = [ANS2] C = [ANS3] D = [ANS4] (4)
