showed substantial white matter atrophy in frontal brain regions over a four-year period, a process that was largely independent of gray matter change.;Given the changes in white matter observed in healthy aging, the next study examined the extent to which white matter changes impact function. Th...
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...
OBJECTIVE: To investigate the topographic changes of white matter (WM) integrity and cortical thickness related to gait disturbances and determine whether these neural correlates mediate the association between cerebral small vessel disease (CSVD) and gait disturbances. METHODS: A total of 129 patients ...
The brain contains both gray matter and white matter. The gray matter is made up up of the neurons that have non-myelinated axons. The white matter is made up of neurons that have myleniated axons. The myelin sheath is white. The primary thinking, perceiving and cognitive functions of th...
Previous studies reported that depressed subjects had more white matter hyperintensities on magnetic resonance imaging scans than control subjects, but the subjects had cerebrovascular disease risk factors. This study used subjects with a history of recurrent major depression and matched comparison subjects,...
MN Smolka24,25, G Schumann6,19, J-L Martinot2,3,4 and the IMAGEN consortium (www.imagen-europe.com)26 Abnormalities in white-matter (WM) microstructure, as lower fractional anisotropy (FA), have been reported in adolescent-onset bipolar disorder and in youth at familial risk for bipolarity...
The female uses in the cerebrum the white matter is masculine 10 times, but in the masculine use cerebrum gray matter is feminine 6.5 times.The gray matter includes the information processing center, the white matter function is connects these information processing center, forms the network.It ca...
A universal scaling law between gray matter and white matter of cerebral cortex. Presents an analytical theory for the gross organization of cortical gray matter and the associated white matter of the cerebral cortex. Close relationship... Kechen,Zhang,Sejnowski,... - 《Proceedings of the ...
We aimed to evaluate whether white and gray matter microstructure changes observed with magnetic resonance imaging (MRI)-based diffusion tensor imaging (DTI) can be used to reflect the progression of chronic brain trauma. The MRI-DTI parameters, neuropat
We accurately measured white matter (WM) and gray matter (GM) from three-dimensional (3D) volume studies, using a fuzzy classification technique. The new segmentation method is a modification of a recently published method developed for T1 parametric images. 3D MR images were transformed into pseu...
