al., 2004), Talairach transformation, segmentation of sub cortical white matter and deep gray matter structures (hippocampus, amygdala, caudate, putamen, ventricles), intensity normalization, tessellation of the gray matter white matter boundary, automated topology correction and surface deformation following intensity gradients. Following these procedures, 38 regionally segmented volumes for gray and white matter structures were obtained and carried forward in the analysis. Specific regions are shown in Table 2.
