What term do sleep researchers use to designate Stages 1–4 of sleep?
A) REM sleep
B) Non-REM sleep
C) REMN sleep
D) paradoxical sleep
Answer: B
Rationale: REM is sometimes known as paradoxical sleep because the EEG waves appear to represent a state of wakefulness, but it is in fact a stage of sleep, during which body movements are inhibited. The REM pattern is so distinct that the first four stages are known collectively as non-REM or NREM sleep.
