Researchers have been able to conduct scans on people's brains to reveal how we navigate from one place to another.

Brain scans have revealed the workings of the brain’s GPS that underpin our decisions as we navigate towards a destination.
Two areas of the brain appear to take turns as our internal global positioning system and work together to steer us through the environment. The brain regions take on different roles to meet our needs, with one keeping track of the distance to our destination as the crow flies, and the other chipping in to calculate the actual distance of the route ahead when we reach a junction.
