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...
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, neuropathologic changes, and behavioral performance of ...
While in this photograph, the gray matter is more of a yellowish cream, the white matter is as a white as the name would imply. The boundaries where the gray matter and the white matter come together are known as the “gray matter/white matter interface.” In such areas, there is a s...
MR volume segmentation of gray matter and white matter using manual thresholding: dependence on image brightness. PURPOSE: To describe a quantitative MR imaging segmentation method for determination of the volume of cerebrospinal fluid, gray matter, and white matter in... GJ Harris,PE Barta,LW ...
Gray matter volume alterations in patients with strabismus and amblyopia: voxel-based morphometry study Voxel-based morphometry (VBM) was used for gray matter and Tract-based spatial statistics (TBSS) was used for white matter data analysis. VBM revealed ... T Su,P Zhu,B Li,... - 《Scienti...
Diffusion tensor imaging and voxel-based morphometry were used to quantify white matter integrity and gray matter volume (GMV), respectively. Stepwise regression was used to evaluate the contribution of clinical and demographic variables to TMS-evoked BOLD. Consistent with previous studies, frontal pole...
摘要: Derived from the Greek words hydro, meaning water, and cephalus, meaning head First described by Hippocrates, but it remained an intractable condition until the twentieth century, when shunts and other neurosurgical treatment modalities were developed Defined as dilation of cerebral ventricles...
Cognitive function is associated with GM atrophy and depressed mood is associated with frontal WML. This indicates that although both often occur together, depressed mood and cognitive impairment have different pathological correlates. 展开 关键词: White matter lesion Gray matter atrophy Depression Mood ...
Conclusions During the early stage of first-episode schizophrenia,there are structural abnormalities in the white matter and gray matter,especially in the white matter. 展开 关键词: Schizophrenia Gray matter White matter Magnetic resonance imaging Statistical parametric mapping ...
BACKGROUND: There is limited and inconclusive evidence that space environment, especially microgravity condition, may affect microstructure of human brain. This experiment hypothesized that there would be modifications in gray matter (GM) and white matter (WM) of the brain due to microgravity. METHOD...
