1.9 million euro ERC grant awarded to Simon Hanslmayr to explore memory coding in human brains. Episodic memory is the time machinery that allows us to mentally travel back in time in order to relive past experiences, often in great sensory detail. These memories are highly associative and very information rich, but how are these memories coded in human brains? Neural oscillations, regulating the synchrony of neural assemblies, are ideally suited to accomplish these two functions, but it is still unclear how synchronization and desynchronization are orchestrated in neural networks to achieve persistent memory. This is the question tackled by Simon and his team in this ERC-funded project.
