Pigeons Have GPS Built Into Their Brain

That
GPS unit on your car sure is fancy, but pigeons have got you beat: they
have GPS built right into their brain!

Researchers have spotted a group of 53 cells within pigeons’ brains
that respond to the direction and strength of the Earth’s magnetic field.

The question of how birds navigate using – among other signals
– magnetic fields is the subject of much debate.

These new "GPS neurons" seem to show how magnetic information
is represented in birds’ brains.
