概括

宫性 dystonia (CD) 的患者表现出重新组织的白质 (WM) 结构网络,显示出改变的网络隔离和弹性. 这些CD患者的网络变化是使用扩散张量成像 (DTI) 和图形理论分析来确定的.

科学领域:

神经成像是一种神经成像.
神经科学是一个神经科学.
医疗成像医学成像

背景情况:

宫性 dystonia (CD) 患者表现出改变的皮层-亚皮层白质 (WM) 捆.
在CD中对WM结构网络的重组仍然不清楚.
调查WM网络的拓变化对于理解CD至关重要.

研究的目的:

与健康对照组 (HCs) 相比,研究CD患者的大规模WM结构网络的拓变化.
探索与CD的临床表现相关的网络变化.

主要方法:

扩散张力成像 (DTI) 用于30名CD患者和30名HC患者.
在WM网络建设中,使用了BNA-246地图和确定性轨迹学.
图形理论分析评估了全球和本地网络属性,并使用AAL-90图谱进行了可重现性分析.

主要成果:

癌症患者表现出改变的网络隔离和弹性,增加了局部效率和分类能力.
与HC相比,在CD患者中观察到网络强度的显著下降.
复制性分析证实CD患者的分类性和网络强度增加.

结论:

该研究表明,CD患者的大规模WM结构网络的重组.
这种重组的具体原因,无论是与 dystonia 特定的还是与高动力运动相关的,都需要进一步调查.

Spinal Cord: Cross-sectional Anatomy

The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

Central to the gray matter is...
