Every day we experience new events, improve our skills, meet new people, or learn new information about those we already know. What happens to all of these memories when we go to sleep? During sleep, the brain doesn't simply store what we've learned: it reorganizes it, abstracts it, and quietly rewrites it into something more flexible and durable. Some memories are strengthened, others discarded, and some are transformed into general rules. My PhD supervised by Fosca Al Roumi (UNICOG, Neurospin) and Thomas Andrillon (ICM) investigates exactly this process: how sleep shapes the way we learn, and whether an overnight rest helps the brain move from memorizing specific experiences to understanding the patterns that underlie them.
