Clusters showing significant surface expansion of the lateral ventricles in the methamphetamine group. Clusters illustrated in the figure denote the significant surface expansion in the methamphetamine group relative to the control group. In order to correct for multiple comparisons, surface-based cluster-size exclusion with the initial threshold of p < 0.005 was used. Any inflation or deflation in surface metrics within a cluster containing less than 20 vertices was excluded. Four clusters of surface expansion related to methamphetamine dependence (red arrows) were found while there was no significant deflated region. (a) Clusters of surface expansion in regions adjacent to the bilateral ventral striatum. (b) A cluster of surface expansion in regions adjacent to the right medial frontal lobe. (c) A cluster of surface expansion in regions adjacent to the right thalamus.
