The Restoring Active Memory team at University of Pennsylvania has shown that during both spatial navigation and memory recall, the brain produces low-frequency oscillations called theta waves. The finding suggests that the brain structures responsible for helping people navigate in the world may also create mental maps of prior experiences.

The research illuminates some of the neural underpinnings of memory, particularly how the brain binds, stores, and accesses items that are somehow related to one another, and also how that mechanism of memory might generalize across domains (e.g., verbal vs. spatial).
