Outline how the behaviour of the brain was measured:
There were three different ways in which they measure the activity of the brain.
1) They used and MRI scanner, these scans were then looked at by an independent doctor at the hospital who did not know which scans had come from the taxi drivers.
2) VBM was then used to analyse the 26 seperate slices of the brain. Voxel-based Mophology measures the density of grey matter in the brain and provides a 3D measurement of volume of an area.
3) Pixel Counting was also used. This is the procedure of counting the number of pixels in the MRI scan. A pixel is a 2D measurement of an area. The areas they measured were calculated by taking whole slice images of the hippocampi.
