Where am I? How our brain works as a GPS device

We've all experienced the feeling of not knowing where we are. Being disoriented is not pleasant, and it can even be scary, but luckily for most of us, this sensation is temporary. The brain employs a number of tricks to reorient us, keeping our confusion to a minimum and quickly pointing us in the right direction. Research has suggested that animals and young children mainly rely on geometric cues (e.g. lengths, distances, angles) to help them get reoriented.
