Answer to Question 1

ANS: D
The electrooculogram records eye movements during sleep and allows the clinician to differenti-ate non-REM sleep states from REM sleep states. An electromyogram records arousal responses and sleep movements. An electroencephalogra m measures brain wave activity during sleep. An electrocardiogram measures cardiac activity.

Answer to Question 2

ANS: B
The height or depth of the deflection depends on the movement of the eyes relative to the fixed electrodes. Eye movement away from the electrode shows an upward deflection on the elec-trooculogram, and eye movement toward the electrode shows a downward deflection.
