Sleep Promoting Improvement of Declarative Memory
This chapter summarizes a series of our own studies in humans; supporting a beneficial influence of slow-wave sleep on declarative memory formation and try to identify some mechanisms that might underlie this influence. Memories may serve as fond reminders of the past, but they also allow us to achieve learning goals and expand our educational horizons in the here-and-now. Implicit memory is a type of longterm memory that stands in contrast to explicit memory in that it doesn’t require conscious thought. Episodic memory is one type of explicit memory. Episodic memory is autobiographical: it provides us with a crucial record of our personal experiences. Procedural memory is the type of implicit memory that enables us to carry out commonly learned tasks without consciously thinking about them. The covert reactivation of neuronal populations used for encoding the respective materials during prior learning is thought to be a central mechanism for memory consolidation during sleep.
