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。

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。

Detection of regional cerebral blood volume, regional cerebral blood flow, average pass time and peak time of the contrast medium in lesion area and the contralateral area; Comparison of the amount of connecting fibers between left corticospinal tract and left Broca and Wernicke areas.

病变部位及对侧的局部脑血容量、局部脑血流量、对比剂平均通过时间、达峰时间的测定，左侧皮质脊髓束及Broca区与Wernicke区之间的联系纤维数量与对侧相应区域的比较。

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.
