A,B. Dreaming of a spatial learning task is associated with enhanced navigation performance at delayed retest, while thinking of the task during wakefulness is unrelated to later performance [66]. Error bars represent ±S.E.M.

Following training on an engaging downhill skiing arcade game, 30% of 386 sleep onset mentation reports contained task-related imagery or thoughts [29]. Representation of the game primarily took the form of sensory imagery as opposed to thought, and most often bore a direct, unambiguous relationship to the game.

A. In animals, memory reactivation is seen as patterns of cell firings during waking exploration of an environment (Top) that are reiterated in subsequent NREM sleep (Bottom), albeit on a faster time scale. Vertical bars represent the time of peak firing for 10 individual cells demonstrating clear place fields in the training environment [79]. B. In humans, evidence of reactivation has been reported in imaging studies demonstrating that brain regions engaged during task encoding are again active during post-training sleep. In this example, “reactivation” of hippocampal activity during post-training sleep (Right) predicted overnight improvement in memory performance on a spatial learning task (Left).
