These results provide novel insights into the differential reprogramming capability between the astrocytes in the grey matter versus the white matter, and highlight the impact of regional astrocytes as well as microenvironment on the outcome of glia-toneuron conversion. Since human brain has large ...

We first compared grey matter volume (GMV) and white matter indices (fractional anisotropy (FA) and mean diffusivity (MD) values) in LBD patients with VH to age matched healthy controls to assess the differences related to LBD. Then, to test specific hypotheses related to MVH and CVH ...
MR spectra acquired with single voxel PRESS (echo time 35ms, repetition time = 1.5s, 128 averages) of parietal white matter (WM) and parieto/occipital grey matter (GM) were analyzed with automated LCModel software and absolute metabolite concentrations were obtained. Metabolite versus age curves...
MRI features of grey matter atrophy and White Matter Hyperintensities (WMHs) of cerebrovascular origin have been linked to cognitive symptoms in Parkinson's disease (PD) (Yau 2018, Dadar 2018). Here we assess the relationship between WMH burden, gray matter atrophy in the Hippocampi and cognitive...

of the brain made up of gray matter to communicate with one another. Gray matter hubs, on the other hand, are far more localized. In this new effort, the researchers looked at the impact of brain damage on hubs in gray matter versus similar types of damage to hubs in white matter. ...

Anisotropic power (AP) maps [53], which are diffusion-derived maps that contain a good contrast in both grey and white matter, were also computed at this stage. MegaTrack [54], a semi-automatic group dissection approach, was adopted to account for the large number of subjects. For this ...
Patients with bipolar disorder (BD) show alterations in both gray matter volume (GMV) and white matter (WM) integrity compared with healthy controls (HC). However, it remains unclear whether the phenotypically distinct BD subtypes (BD-I and BD-II) also exhibit brain structural differences. This...
