Which of the following statements about neural activity during sleep is accurate?

• A. There is no neural activity during sleep.
• B. Neural activity during sleep is exclusively directed toward dreaming.
• C. Neural activity during sleep serves multiple functions, including memory consolidation and restoration, not just dreaming.
• D. Dreaming occurs throughout all stages of sleep and is the only purpose of neural activity during sleep.

Answer: (C)

Verified step by step guidance

1. Step 1: Understand that neural activity during sleep is not absent; the brain remains active throughout different sleep stages.
2. Step 2: Recognize that neural activity during sleep serves multiple functions, such as memory consolidation, restoration of brain functions, and processing emotions.
3. Step 3: Note that dreaming is one aspect of neural activity during sleep but is not the sole purpose; dreaming can occur in various sleep stages, including REM and non-REM sleep.
4. Step 4: Evaluate each statement by comparing it to established scientific knowledge about sleep neuroscience, focusing on the roles of neural activity beyond just dreaming.
5. Step 5: Conclude that the accurate statement is the one acknowledging multiple functions of neural activity during sleep, including but not limited to dreaming.
