Question
ompared with the brain waves observed in stage 2 sleep, the brain waves in stage 3 sleepMultiple Choiceare more rapid.have higher peaks.are interrupted by sleep spindles more frequently.have lower amplitude.
Solution
The brain waves in stage 3 sleep have higher peaks compared to those in stage 2 sleep. This is because stage 3 sleep, also known as deep sleep, is characterized by delta waves, which are the slowest and highest amplitude brain waves. They are not more rapid, nor are they interrupted by sleep spindles more frequently. Sleep spindles typically occur in stage 2 sleep, not stage 3. The amplitude of the waves is not lower in stage 3; in fact, it's the opposite. Therefore, the correct answer is "have higher peaks."
