LECTURER: Tonight we'll examine how sleep consolidates memory. During slow-wave sleep, the hippocampus replays the experiences of the day, strengthening the connections that store them. Without adequate sleep, students show much weaker recall of factual lists, particularly after the first day or two.

Recent experiments used word-pair tasks. Participants who napped for ninety minutes clearly outperformed those who stayed awake. Interestingly, caffeine taken before bedtime reduced slow-wave sleep, even when the subjects felt that they had slept perfectly normally.

Researchers also studied shift workers. Their rotating schedules disturbed the workers' circadian rhythms and increased errors in procedural tasks, such as work on an assembly line. The lecture therefore concludes that keeping consistent bedtimes supports both academic and occupational performance.
