A Role of Sleep in Forming Predictive Codes

Cognitive Neuroscience of Memory Consolidation

Abstract

Memory consolidation is traditionally described and investigated in terms of the strengthening of memory traces, particularly those pertaining to recently encoded information. Over the last decade, this traditional view has been complemented by conceptual and empirical work indicating that memory consolidation is both selective and transformative: only a subset of new experiences undergoes consolidation, and in this subset, representations are not merely strengthened, but also restructured. In this chapter, we briefly review evidence for selection and transformation of memory traces during consolidation, and the pivotal role of sleep in these processes. We will then argue that these findings might be best understood in the context of recent Bayesian theories of brain function, and we will show how this perspective helps generate new hypotheses concerning the mechanisms of memory consolidation during sleep.
