Has the scent of freshly baked chocolate chip cookies ever taken you back to afternoons at your grandmother’s house? Has an old song ever brought back memories of a first date? The ability to remember relationships between unrelated items (an odor and a location, a song, and an event) is known as associative memory.
Psychologists began studying associative memory in the 1800s, with William James describing the phenomenon in his 1890 classic The Principles of Psychology. Scientists today agree that the structures responsible for the formation of associative memory are found in the medial temporal lobe, or the famous “memory center” of the brain, but the particular cells involved, and how those cells are controlled, have remained a mystery until now.
