In addiion to increasing amount of informaion in memory, sleep also stabilizes the memory traces makes them more resistant to interference: proposed that hippocampal memory traces are reacivated during sleep and transferred to sites in the cortex. Sleep can also improve implicit or non-declaraive memories. Can make motor skills more stable and resistant to interference. Consolidaion during sleep can also produce a gain in skill. Sleep (especially rem sleep) has an enhancing efect on emoional memories. Amygdala: area of brain crucial role in making signiicant experiences more memorable.
