Scientists Discover Brain's Tiny Region That Segments and Stores Memories

Scientists discovered that a small brain region called the locus coeruleus acts as a 'reset button' during meaningful changes in experiences, helping to organize memories by signaling the start of new events and separating them into distinct memories. This process is crucial for understanding how we perceive and remember events, and disruptions in this system may relate to memory disorders like PTSD and Alzheimer's disease.
