Voxel-based morphometry is an automated technique for MRI analyses, developed to study differences in brain morphology and frequently used to study patients with diverse disorders. In epilepsy, it has been used to investigate areas with reduction or increase of gray and white matter, in different ...

Of all the morphology metrics studied, the spine density was the only one to show significant correlation with the VBM signal. These data demonstrate that learning-induced structural changes detected by VBM may be partially explained by increases in dendritic spine density. 展开 ...
Dynamics and Morphology of Nanoparticle-linked Polymers Elucidated by NMR Nanoparticles are frequently modified with polymer layers to control their physical and chemical properties, but little is understood about the morphology and dynamics of these polymer layers. We report here an NMR-based investigatio...
In addition to changes in the dendritic spine density and morphology, the use of the Thy1-YFP line also afforded for the ability to measure changes in the layers V and VI neuron soma diameter. Supplementary Fig. 2a shows the division of layers V and VI of the AC. Supplementary Fig. 2b...
Combined with VBM-MRI, a better understanding of the changes in brain function and morphology in Meige syndrome can be obtained. Another limitation of our study is that the cohort is composed of a mix of significantly different phenotypes of Meige syndrome (oromandibular, blepharospasm and ...
? Brain morphology and cognition of patients with temporal lobe epilepsy were compared. ? Voxel-based morphometry revealed a gray matter excess in the early-onset group. ? Gray matter excess is discussed as reflecting disruption of normal brain development. ? The results support the idea of early...
Moreover, it was found to perform substantially better than the voxel-based morphology method of SPM'99. Improved sensitivity was achieved at the expense of human effort involved in defining a number of sulcal curves that serve as constraints on the 3D elastic warping. 展开 ...
