please select the best answer from the choices provided

t
f

Explanation:

Analyze brain activity during REM sleep

During Rapid Eye Movement (REM) sleep, brain activity does not decrease; instead, it increases significantly, resembling the high-frequency, low-amplitude beta waves seen during alert wakefulness.

Compare with other sleep stages

Non-REM (NREM) sleep stages, particularly deep slow-wave sleep (Stage 3/N3), are characterized by greatly decreased brain activity and slow delta waves, whereas REM sleep is a highly active state often referred to as "paradoxical sleep."

Determine the truth value

Since brain activity increases rather than decreases during REM sleep compared to other stages, the statement is false.

Answer:

• T
• F (Correct answer)
