Figure 2. Distribution of striatal activity during right-hand finger tapping.

Figure 2

Voxel-based maps of significant brain activity for controls (top) and chronic cocaine users (bottom) during internally-guided (left) and externally-guided (right) finger-tapping relative to rest. These data were modeled across all subjects in each group in order to get a voxel-based representation of the distribution of activity within the striatum. The colorbar indicates z-scores from voxels that met criteria of a minimum cluster size of 25 voxels with a threshold of statistical significance at p < 0.001 for uncorrected values.
