Cliff is hooked up to an EEG in a sleep lab. He has been asleep for just over an hour when his EEG starts to show low amplitude, irregular wave patterns. Cliff’s hands and feet begin to twitch, and his eyes begin to dart back and forth under his eyelids. The researcher who is monitoring Cliff’s sleep can conclude that Cliff:A) has just entered Stage 4 sleep
B) has just entered REM sleep
C) suffers from narcolepsy
D) is having a seizure
E) is experiencing severe case sleep apnea and needs medical attention

B) has just entered REM sleep

Explanation:

REM sleep is deep sleep. It can also be called "rapid eye movement", because when an individual reaches this stage of sleep, he usually presents a rapid movement of the eyelids. Sleep Rem also allows the individual to show irregular and low amplitude wave patterns, in addition, in some cases it is normal for the individual to show involutory muscle movements in the hands and feet, similar to what Cliff is showing.

REM sleep also promotes breathing and a greater supply of oxygen to the body, in addition to being essential for cognitive development, body repair and memory processing.
