This helps differentiate it from diseases that affect the motor cortex or corticospinal pathway.

这一点使其区别于运动皮质或皮质脊髓通路病变。

Damage to the corticospinal tract causes weakness and problems with voluntary muscle movement below the level of the spinal cord segment.

伤皮质脊髓束可以导致感觉平面以下的肌肉无力随意运动障碍。

Brown-Sequard Syndrome is a condition associated with hemisection of spinal cord, which usually damages descending corticospinal tracts, ascending dorsal column tracts and spinothalamic tracts.

脊髓综合征，是一种与脊髓伤相关的疾病，通常会伤下行的皮质脊髓束、上行的脊髓背侧束与脊髓丘脑束。

When the corticospinal tract is affected, a person will have problems with voluntary movement, and when the spinothalamic tract is damaged, a person will have problems sensing pain.

当皮质脊髓束受时，患者会有随意运动障碍；当脊髓丘脑束受时，患者会有痛觉丧失。

Once your brain receives sensory information, it sends a motor signal down the upper motor neurons through the corticospinal tract in the midbrain, and cross to the opposite side at the medulla before continuing down the spinal cord.

当大脑接收到感觉信息时，它通过中脑的皮质脊髓束向上运动元发送运动信号，先交叉至对侧延髓，然后继续下行。
