“…On the other hand, postmortem tracers have no practical value due to their glacial pace (Sparks et al, 2000). But, researchers are now equipped withmodern imaging technologies such as structural magnetic resonance (Liu et al, 2009a;Wang et al, 2012;Li et al, 2013a) or fMRI associated with voxel-based morphometry approach (Yuan et al, 2010b;Qiu et al, 2013), regional homogeneity tool , pharmacological MRI (phMRI) (Denier et al, 2013a) or fMRI combined to a pulsed arterial spin labeling (Denier et al, 2013b) and quantitative diffusion tensor imaging (Liu et al, 2008;Bora et al, 2010;Wang et al, 2011;Lin et al, 2012;Zhang et al, 2013).Numerous imaging studies have shown structural deficits that are associated both gray (Liu et al, 2009a;Yuan et al, 2009Yuan et al, , 2010bWang et al, 2012;Denier et al, 2013a;Qiu et al, 2013) and white matter (Liu et al, 2008;Bora et al, 2010;Wang et al, 2011;Lin et al, 2012;Li et al, 2013c;Zhang et al, 2013) reductions, perfusion's decrement (Denier et al, 2013a(Denier et al, , 2013b, diminished homogeneity and abnormal cortical thickness (Li et al, 2013a). Moreover, few studies associated structural reductions with rsFC impairments (Liu et al, 2009b;Yuan et al, 2009Yuan et al, , 2010aYuan et al, , 2010cMa et al, 2010) despite the fact that their causal relationship remains unknown.…”
