For many of us, navigating the world seems like an impossible task without our smartphone. But a new study suggests humans are more adept at making our way from A to B than we might have realised. Scientists have found we have an'internal neural compass' in our brains that lets us orientate ourselves and navigate through an environment. This compass – which takes the form of an electrical signal transmitted by nerve cells – tells us we're about to head in a new direction. What's more, once we've reoriented ourselves, it lets us know that we're travelling along a new path – so eastwards instead of northwards, for example.
