Figure 3. The activation and deactivation maps from two subjects' bilateral hand data.

The voxels with Z-scores greater than 5.0 are considered to be activated, while the voxels with Z-scores less than −5.0 are considered to be deactivated. These voxels are mapped in different colors according to their Z-score values. (a) and (b) are for the left and right hand data, respectively, from subject one, while (c) and (d) are for the left and right hand data, respectively, from subject two.
