Significant changes (increase of cerebral gray matter) during the time of skilled performance (scans 2) compared to time point one (before juggling). This pattern reversed when study participants were examined at time points 5 and 6 (following the weeks of exercise). The changes are tabulated in terms of the brain region and the corresponding Brodmann's area (BA). The x, y, z co-ordinates are according to the MNI atlas. Each location is the peak within a cluster (defined as the voxel with the highest Z-score).
