Slow wave sleep has been considered an important aspect of memory consolidation, most commonly through a model known as active systems consolidation. Newly encoded memories are repeatedly activated, driven by slow oscillations that occur in the neocortex. A widely accepted view is that emotional memories are preferentially consolidated during sleep making them easily obtainable for retrieval. However, recent meta-analyses of sleep, emotion, and memory have suggested that this effect may not be as robust as we once thought. A relatively new way to investigate sleep and emotional effects on memory is with a pattern separation task called the Mnemonic Similarity Task (MST). The current study examined pattern separation and item recognition using an emotional variation of the MST consisting of negative and neutral images.
