Most of us also know how good we are at navigating. If you rate yourself on a scale of one to ten, a scientific test will likely give you about the same score.

Scientist and science writer Christopher Kemp rates himself a one out of ten. He sometimes gets lost in his own neighborhood. His lack of navigation skills align with a condition known as developmental topographical disorientation, or DTD, which is passed down genetically. His wife, in comparison, is excellent at finding her way, and can easily orient herself in new places. That stark contrast inspired an investigation into the neuroscience of navigation.

Why do some humans navigate better than others? What happens when we rely on GPS devices instead of our internal sense of direction? What's going on inside our brains when we try to find our way?

Kemp helps us navigate these questions and more.
