CAN ANYONE HELP ME ANSWER THIS QUESTION!? I'VE READ THE QUESTION OVER AND OVER BUT IT IS CONFUSING ME....
At first the subject had difficulty falling asleep in the sleep lab, but finally drifted into sleep and was not awakened when a student researcher knocked a can of soda off of the desk. The EEG is displaying a slow regular pattern with occasional sleep spindles. The researchers feel confident that the subject is:
a)about to wake up
b)now in stage 2 of the sleep cycle.
d)in REM sleep.
The question is asking what sleep cycle this subject is in.
then the answer is B, I assume. right?
I don't know. Check your text.
Stage N2 is characterized by sleep spindles ranging from 11 to 16 Hz (most commonly 12–14 Hz) and K-complexes. During this stage, muscular activity as measured by EMG decreases, and conscious awareness of the external environment disappears. This stage occupies 45–55% of total sleep in adults.
