Figure 1.

Voxel-Based Morphometry results on gray matter. Cold color bar shows regions where gray matter volume is lower in regular smokers compared with occasional ones. Hot color bar represents the opposite contrast. Maps are thresholded at P<0.005 and k>60 and superposed on a standard brain in the MNI space. Figure shows results in planes centered at −26, 7, 14 mm and −48, 10, −19 mm. Color bars represent T score.
