概括
在非初级运动区域,特别是背部前运动皮质 (PMd) 的皮质脊髓 (CST) 损伤负荷强烈地预测了中风后的长期运动恢复. 微结构完整性也起着作用,但损伤负载是预测结果的更主要因素.
科学领域:
- 神经科学是一个神经科学.
- 神经学 神经学
- 放射学 放射学是一门学科.
背景情况:
- 皮质脊柱体 (CST) 损伤预测了中风后的运动缺陷.
- 从非初级动力区域中CST子路径的作用尚未完全理解.
研究的目的:
- 调查CST子路径的微结构完整性和病变负荷 (LL) 在2周后是否预测中风后2,6和12周的运动结果.
主要方法:
- 扩散光谱成像 (DSI) 量化了CST的完整性.
- 结构性MRI测量了CST损伤负荷 (LL).
- 逐步的多重线性回归分析了预测值.

Direct Motor Pathways
2.5K
The direct motor pathways, also known as the pyramidal tracts, are a group of neural pathways that originate in the brain and descend through the spinal cord. They control the voluntary movement of the body. There are two major direct motor pathways: the corticospinal and the corticobulbar tracts.
The corticospinal tract is responsible for the voluntary movement of the limbs and trunk. It originates in the cerebral cortex of the brain and descends through the cerebrum's internal capsule and...

Indirect Motor Pathways
1.7K
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...
