An engineer studying cognitive function during sleep monitors a subject whose adenosine receptors are experimentally blocked. Which outcome is most likely regarding the subject's sleep architecture?

A)Increased REM sleep latency
B)Suppressed slow-wave sleep duration
C)Reduced memory consolidation efficacy
D)Elevated melatonin production peak

💡 Explanation

Blocking adenosine receptors disrupts sleep homeostasis because adenosine accumulation normally promotes slow-wave sleep, crucial for memory consolidation. Therefore, memory consolidation is reduced, rather than affecting REM sleep or melatonin production directly, as adenosine's primary role is in promoting deep sleep.
