Read the passage and answer the question:

"Neuroscientific research demonstrates that slow-wave sleep is essential for synaptic consolidation. During non-REM sleep, the hippocampus replays neural representations of newly acquired procedural and declarative memories, transferring them to the neocortex for long-term storage."

Based on the passage, what critical cognitive function occurs during slow-wave sleep?

Answer and explanation

Correct answer: B. newly learned memories are transferred to the neocortex for long-term storage

  1. Step 1: Trace the neurological mechanism: 'During non-REM sleep, the hippocampus replays neural representations... transferring them to the neocortex for long-term storage'.
  2. Step 2: Slow-wave sleep facilitates memory consolidation and cortical transfer.
Answer
newly learned memories are transferred to the neocortex for long-term storage.
Why not the others: 'the brain permanently erases all factual information acquired during the day' contradicts memory consolidation; 'the hippocampus increases physical brain volume by generating millions of neurons' misinterprets synaptic consolidation as massive neurogenesis; 'motor reflexes operate at peak velocity while conscious awareness is heightened' describes wakefulness or acute stress, not deep sleep.
