The brain does most of its housekeeping while we sleep, and one housekeeping duty in particular – waste disposal – seems to be acutely sensitive to a lack of sleep. Depression. Insomnia, defined as persistent difficulty initiating or maintaining sleep, is known to cause daytime cognitive impairments including reduced memory functioning. According to Ellenbogen et al. (2006),the search for mechanisms underlying sleep-dependent consolidation of declarative memories in humans must rely on examination of specific properties of sleep physiology. By showing that a specific form of memory consolidation crucially depends on a brain property unique to sleep, the connection can be proving.

By "depth of processing", we mean, the way in which a person thinks about a piece of information, for example, a shallow level of processing of a word would be to skim over a sentence and to understand the sentence without dwelling on the individual word.
