Brain researchers win Nobel Prize; UK WORLD &.
AN American-British scientist who helped to uncover the brain's "inner GPS system" was yesterday jointly awarded the 2014 Nobel Prize in Medicine more than 40 years after his research.
John O'Keefe, a professor of cognitive neuroscience at University College London, made the key discovery in understanding the brain's navigation system in 1971 when he identi-fied "place cells" which map the environment around us.
It was 34 years later in 2005 that Norwegian scientists, married couple May-Britt Moser and Edvard Moser, found a second type of nerve cell - the "grid cell" which generates a co-ordinate system for path-finding.
The Nobel Prize assembly said together the three scientists 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?"
