VBM: Taxi drivers had increased grey matter volume in the right and left posterior hippocampus

Pixel counting: showed no significant difference in overalll volume of hippocampi

Correlational analysis found that there was a postive correlation between the lenght of time spent as a taxi driver and the volume of the right posterior hippocampus


Hippocampus shows plasticity, Volume increases with navigational experience

Right hippocamups holds mental maps.
