Like digital cameras, brain ‘geotags’ new memories

When most people recall fond memories, they not only remember what happened, but also where they were when it happened.

According to new research, the brain uses special cells in the hippocampus to “geotag” episodic memories, in much the same way some digital cameras and smartphones save the GPS coordinates of each image that is captured. This process occurs to help the brain create, store and later recall memories.

As a result of this geotagging, memories about places and events are “fused together,” says Michael Kahana, a psychologist at the University of Pennsylvania, and one of the study’s authors. “You come to a location where something happened and it reminds you of an event,” he says. “Or you think of an event and it reminds you of the place where it happened.”
