However, more recent meta-analyses extended these findings to regions outside the frontal-subcortical areas, including alterations of gray matter density in the superior parietal lobe (Peng et al., 2012; Radua & Mataix-Cols, 2009) supramarginal gyrus (Rotge et al., 2010), and cerebellum (de Wit et al., 2014).
