概括

在中脑动脉 (MCA) 中风后,牙大脑皮层管 (DTCT) 的完整性可以预测长期的上肢运动功能. 这一发现突出了小脑在中风后的运动恢复中的作用.

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:

小脑对于运动控制,协调和学习至关重要.
皮层-小脑连接在中风后的运动恢复中的作用,特别是对上肢的作用,仍未得到充分探索.
这项研究调查了亚急性中风患者皮质大脑管完整性的预测价值.

研究的目的:

评估亚急性中脑动脉 (MCA) 中风患者中关键皮质-小脑道的微结构完整性.
为了确定这些通道的完整性是否可以预测慢性上肢运动功能.
探索中风相关损伤与运动恢复之间的关系.

主要方法:

对25名亚急性MCA中风患者和25名健康对照患者的扩散-张张成像 (DTI) 的回顾性分析.
评估皮质脊髓管 (CST),牙支柱状皮质管 (DTCT) 和皮质脑脊髓管 (CPCT) 的微结构完整性.
线性回归模型被用来预测基于通道完整性的慢性上肢运动功能.

主要成果:

脑卒中患者在受影响的DTCT和CST的结构完整性明显受损,与对照和未受影响的路径相比.
一个回归模型包含了CST和DTCT的微分异构 (FA) 非对称指数,最好预测慢性上肢运动功能 (R2 = .506,P = .001).
皮质脑小肠道 (CPCT) 完整性在组或半球之间没有差异,也不能预测运动功能.

结论:

在中脑动脉中风 (MCA) 中亚急性阶段,牙牙皮管 (DTCT) 的微结构完整性是慢性上肢运动功能的重要预测因素.
这种预测能力独立于皮质脊柱管 (CST) 状态.
这些发现强调了牙支柱状皮质通路在中风后运动恢复中的重要性.

The Arch of Aorta

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Cerebellum: Anatomical Regions

Cerebellum: Anatomical Regions

The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal to the brainstem. It plays a significant role in motor control, coordination, and proprioception.
Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis. The...
