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.
