The Nobel Prize in Physiology or Medicine 2014 was awarded to John O’Keefe, May-Britt Moser and Edvard I. Moser “for their discoveries of cells that constitute a positioning system in the brain.”

How do we know where we are? How can we find the way from one place to another? And how can we store this information in such a way that we can immediately find the way the next time we trace the same path? This year’s Nobel Laureates have discovered a positioning system, an “inner GPS” in the brain that makes it possible to orient ourselves in space, demonstrating a cellular basis for higher cognitive function.

The Nobel Prize in Physiology or Medicine 2014 was divided, one half awarded to John O’Keefe, the other half jointly to May-Britt Moser and Edvard I. Moserfor their discoveries of cells that constitute a positioning system in the brain.

The discoveries of John O’Keefe, May-Britt Moser and Edvard Moser have solved a problem that has occupied philosophers and scientists for centuries – how does the brain create a map of the space surrounding us and how can we navigate our way through a complex environment?
