My name is Artem, I'm a graduate student at NYU Center for Neural Science and researcher at Flatiron Institute.

In this video, we explore how the brain tags which memories to keep and the role of a special brain wave – a hippocampal sharp-wave ripple in this process.

Our brain constantly decides which memories to keep and which to discard. Recent research highlights how the hippocampus and sharp wave ripples play a crucial role in selecting and consolidating important memories. During sleep, the hippocampus replays experiences in a compressed manner, aiding in memory storage by interacting with the neocortex. Awake ripples tag key events for later consolidation, ensuring efficient and prioritized memory retention.
