Are the brains of London taxi drivers somehow different as a result of exceptional training?
16 right-handed male taxi-drivers were compared with the MRI cans of 50 right-handed male non-taxi drivers.

Is there a relationship between the number of years driving a taxi and the anatomy of the human brain?
Data from the MRI was measured using two different techniques: voxel-based morphometry and pixel counting. Voxel-based morphology: Measured the density of grey matter in the brain. Pixel counting: Counted pixels in the images provided by the MRI scans in order to calculate the area of the hippocampus.
The posterior hippocampus of the taxi drivers were significantly larger relative to those of control subjects and the anterior hippocampus. Voxel-based morphology: The volume of the right posterior hippocampus correlated with the amount if time spent as a taxi driver: The hippocampus may change in response to environmental demands.
