Summary

During sleep, memory traces and the associated neuronal ensembles of wakeful experiences will be reactivated, contributing to the formation of long-term memory. This symposium features new breakthroughs in sleep and memory reactivation. We will present findings on how to increase sleep quality via playing relaxing words and music; how interconnected memories change as a function of reactivation; how to decipher and make meaning of sleep activity using neural contrastive learning; how stress interacts with sleep to influence emotional memory; and how sleep spindles and their refractory periods shape reactivation of emotional memories. Together, this symposium showcases cutting-edge methodologies and the exciting new directions in sleep and memory reactivation, their implications in mental health, cognitive function and neural decoding.
