The core memories are objects of major importance in Inside Out. Like all memory orbs, core memories represent past events of Riley's life. However, they have a much greater importance than usual memories. They represent key moments that have defined Riley's current personality. Core memories appear brighter than any other memory and power each Island of Personality. Core memories are usually stored in the center of Headquarters in a dedicated circular tray, from which they emit a beam of light through a glass tube all the way to their respective Island of Personality.
