Q

What was the procedure of the quasi-experimental part of the study

A

-The taxi drivers all had MRI scans that were compared to those of a control group of 50
-All were right handed males aged 32-62
-The scans of the taxi drivers and control group were analysed in two ways:
-Pixel counting
-Voxel-Based Morphometry 3D
measurement of volume
-In both cases it was the volume of grey matter measured
