Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A technician at a sleep clinic is monitoring a patient’s EEG patterns and, although the pattern suggests wakefulness, he knows that she is asleep. The patient is most likely

A	sleepwalking
B	in a quiet sleep state
C	in stage IV sleep
D	experiencing REM sleep

Explanation:

Detailed explanation-1: -The phasic REM stage is a sympathetically driven sleep state characterized by the presence of rapid eye movements, intermittent muscle twitches, and variations in breathing patterns.

Detailed explanation-2: -EEG recordings during the first hour of sleep. The waking state with the eyes open is characterized by high-frequency (15–60 Hz), low-amplitude activity ( 30 V) activity. This pattern is called beta activity.

Detailed explanation-3: -Briefly, alert wakefulness is associated with a low-amplitude mixed frequency EEG pattern.

Detailed explanation-4: -Brain-wave pattern associated with relaxed wakefulness and drowsiness. Vivid sensory phenomena that occur during the onset of sleep. Short bursts of brain activity that characterize stage2 NREM sleep. Single but large high-voltage spike of brain activity that characterizes stage 2 NREM sleep.
