Brain's GPS system discovery wins Nobel Prize

The Nobel Prize for physiology or medicine has been awarded jointly to UK-based researcher Professor John O'Keefe and Norwegian couple, May-Britt Moser and Edvard Moser, for their discoveries on the brain's "GPS system".

The Nobel Assembly said the three neuroscientists had helped explain how our brains create a map of the space surrounding us.

The prize committee said knowledge about the brain's positioning system may help explain why in Alzheimer's disease patients cannot recognise their surroundings.
