Abstract
How is the long-term storage of neural representations consolidated in the brain? Following sensory input, the brain demonstrates self-organized means of reactivating behaviorally relevant neural representations. The goal of this workshop will be to discuss potential substrates of memory consolidation through the reactivation of assemblies of neurons. Epochs of reactivation occur spontaneously, during restful periods, during various sleep rhythms, et cetera. The role that reactivation plays in memory consolidation and sequence learning is largely unknown and often debated. We will discuss the various paradigms under which reactivation is observed, and the potential impact on plasticity and learning in the brain, along with potential mechanisms. |- |-
