Think you know how to improve your memory? Think again
We all want to improve our memory, but research unveiled by the University of Toronto’s Dr. Katherine Duncan shows that we need to switch our strategies. Memory isn’t a single entity, and separate memory processes, like formation and recall can be enhanced by different brain states. Her results also revealed a major manipulation which triggers these brain states: novelty. The results were presented at the 2017 Canadian Neuroscience Meeting, the annual meeting of the Canadian Association for Neuroscience - Association Canadienne des Neurosciences (CAN-ACN).

The discovery has been years in the making. Back in 2012, Katherine Duncan used functional magnetic resonance imaging (fMRI) to identify how the brain triggers memory states, uncovering a brain region that detects novelty. She then demonstrated that novelty detection acts like a switch, changing how the brain learns and remembers. Finally, she determined the impact of novelty on human memory. As she puts it, “We find that familiarity increased retrieval of other unrelated memories but reduced the chances for memory formation. On the other hand, novelty enhanced the later formation of distinct memories without worrying about previous experiences.”

Duncan suggests we need to revisit how we make memories. “Your ability to remember something doesn’t just depend on the strength of the memory, it depends on the state that you’re in.” Her work also hints at new strategies to improve memory development. “We’re using what we know about the brain to develop memory enhancing tricks, helping people remember faces, names, and places.”
