corticospinal tract

Amyotrophic lateral sclerosis ( ALS ) involves upper neuron , lower neuron and corticospinal tract.

肌萎缩侧索硬化 症 累及部位包括上 、 下运动神经元以及皮质脊髓束.

Combined MR spectroscopic imaging and diffusion tensor MRI visualizes corticospinal tract degeneration in amyotrophic lateral sclerosis

联合应用MR分光镜成像和弥散张力MRI，使肌萎缩侧索硬化患者变性的皮质脊髓束成像

The corticospinal tract is a descending tract that originates in the brain and controls voluntary movements, while the ascending tracts carry sensory information.

皮质脊髓束是一个起源于大脑的下行传导束，控制自主运动，而上行传导束则传递感觉信息。

at this point, ~85% of these upper motor neuronal axons decussate. these fibers then descend as the lateral corticospinal tract.

至此，有大约85%的上位运动神经元轴突交叉成十字形及如皮质脊髓侧束般下降。

Objective To explore the courser of rat corticospinal tract ( CST) in the center neural system and manifestations after spinal cord injury by the Biotin Dextran Amine ( BDA) anterograde neuronal tracing technique.

目的本研究采用生物素标记葡聚糖（biotin dextran amine，BDA）顺行示踪技术来观察大鼠皮质脊髓束（CST）在中枢神经系统中的走行及脊髓损伤后的表现特征。

Objective To establish a combined injury model of cervical dorsal corticospinal tract ( dCST) and red nuclei for the study of plasticity after spinal cord injury.

目的为研究脊髓损伤后的可塑性变化，建立大鼠红核和皮质脊髓背侧束（dCST）联合损伤模型。

there is no decussation in the lateral corticospinal tract after the decussation at the medullary pyramids.

它们在髓状锥体交叉后，不会在皮层脊髓侧束中交叉。
