Brain ’ s ‘ GPS system ’ was only discovered by scientists last year . NYU experts studied brain cells that act as a compass in the brains of mice . They found that during deep sleep , the 'needle ' of the brain compass in the mice moved at the same speed when they were asleep . This is because their blood vessels are relaxed and open up to allow more oxygen into them than normal while sleeping.

Finding could lead to new treatments for navigational problems in humans .
