概括

儿童脊髓损伤 (SCI) 根据损伤的完整性,会对大脑结构产生不同的影响. 完整的SCI (CSCI) 和不完整的SCI (ICSCI) 在感觉运动和认知区域显示出不同的灰色物质重组模式.

科学领域:

神经科学是一个神经科学.
儿科神经学儿科神经学
放射学放射学是一门学科.

背景情况:

大脑灰质 (GM) 和白质的改变在儿科脊髓损伤 (SCI) 中是已知的.
在儿童的完全SCI (CSCI) 和不完全SCI (ICSCI) 之间,大脑重组的差异尚不清楚.

研究的目的:

调查CSCI与ICSCI对儿科患者大脑结构的不同影响.
为了比较儿科SCI亚型和健康对照之间的大脑重组模式.

主要方法:

基于voxel的形态测量和扩散张力成像 (DTI) 分析了GM体积 (GMV) 和DTI指数.
评估了68名患有SCI的儿童 (37名CSCI,31名ICSCI) 和36名健康对照 (HCs).
收集了临床数据,包括运动/感官得分和损伤特征.

主要成果:

在CSCI和ICSCI组中,在感觉运动,情绪和疼痛处理区域都有大脑异常.
与CSCI患者相比,ICSCI患者在左丘脑,右尾状核和左前骨中显著减少了GMV.
在CSCI和ICSCI组之间观察到不同的转基因重组模式.

结论:

Spinal Cord: Cross-sectional Anatomy

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...

Spinal Cord: Gross Anatomy

Spinal Cord: Gross Anatomy

The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...
