Which sleep pattern is described as occurring in the fetus during month 6?

• A. REM sleep
• B. NREM sleep
• C. Deep sleep
• D. No sleep patterns

Answer: (A)

In the sixth month of pregnancy, the brain begins showing REM-like sleep, an active sleep state marked by eye movements, irregular breathing, and occasional fetal movements. This phase reflects ongoing neurological development and helps establish neural connections as the fetus matures. Non-REM or “deep” sleep isn’t the clear pattern described for fetuses at this stage, and saying there are no sleep patterns wouldn’t fit what researchers observe about fetal activity. So, the described sleep pattern fits REM sleep, the active, brain-activating phase seen in the fetus around month six.
