Memories, it appears, are individual distinct experiences that our brains form into information clusters. A team of New York University (NYU) neuroscientists has uncovered how our brains organize these clusters over time. In particular, their study examined a specific dynamic: whether and how the brain would represent the similarities or shared features across individual experiences. Subjects viewed several individual objects (e.g., a tennis racquet) on a computer screen, with each object paired with pictures of four repeating scenes (a beach scene, for example). The study measured subjects’ ability to match the objects with the scenes they viewed at two time periods, immediately after the experiment, and one week later. Over time, the brain had organized the information according to their overlap, somewhat disregarding the non-overlapping details of a specific memory.
