Demographic characteristics of the smokers and never-smokers studied.
Figure 1.
Clusters of increased fractional anisotropy (FA) in smokers compared to healthy non-smokers.
Significant FA alterations as revealed by voxel-based whole brain analysis with SPM5 displayed on the FA average map of the sample. Voxels of increased FA in smokers revealed by SPM5 analysis are displayed with red colour. All clusters shown exceed an uncorrected statistical threshold of P<0.001 and a cluster size threshold of 100 consecutive voxels.
