Sleep and Memory Consolidation
Memory consolidation is an intricate neurobiological process through which temporary, labile memory traces are converted into enduring, long-term representations. Neuroscientists have established that sleep plays an indispensable role in this stabilization. During wakefulness, the hippocampus rapidly encodes novel experiential data and factual knowledge. However, the hippocampus possesses limited storage capacity. During non-rapid eye movement (NREM) slow-wave sleep, sharp-wave ripples in the hippocampus repeatedly replay recently acquired neural firing patterns. This replay coordinates with slow oscillations in the neocortex, gradually transferring synaptic information from the temporary hippocampal repository to permanent neocortical storage networks. Meanwhile, rapid eye movement (REM) sleep appears to facilitate emotional memory regulation and associative creative thinking by pruning redundant synaptic connections. Consequently, chronic sleep deprivation not only impairs immediate attention and vigilance but also substantially impedes the long-term retention of acquired knowledge. It can be inferred from the passage that individuals suffering from chronic sleep deficiency ----.
- A)exhibit an expanded hippocampal storage capacity compared to healthy sleepers
- B)demonstrate exceptional creative problem-solving skills under stress
- C)are likely to struggle with both daytime alertness and recalling newly learned concepts over time
- D)experience a total loss of both motor skills and reflex actions
- E)can easily compensate for lost sleep by taking short ten-minute naps

Doğru cevap: C) are likely to struggle with both daytime alertness and recalling newly learned concepts over time
Çözüm: Son cümlede uykusuzluğun hem anlık dikkati (immediate attention/vigilance) hem de uzun vadeli bilgi tutulumunu (long-term retention) bozduğu belirtilmiştir. Doğru cevap C'dir.
