Damage to the spinothalamic tract causes a loss of temperature and pain sensation.

损伤脊髓丘脑束可以导致痛觉和温度觉丧失。

Finally, the spinothalamic tract is another ascending pathway and it's divided into two parts.

最后的脊髓丘脑束也是一条上行通路，分为两个部分。

First, there's the spinothalamic tract, which is an ascending pathway and it's divided into two parts.

首先是脊髓丘脑束：它是一条上行通道，分为两部分。

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.

脊髓半切综合征，是一种与脊髓半切损伤相关的疾病，通常会损伤下行的皮质脊髓束、上行的脊髓背侧神经束与脊髓丘脑束。

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.

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

So, damage to the right spinothalamic tracts will cause loss of pain, temperature and crude touch sensation from the opposite or left side, beginning one or two segments below the lesion.

所以，右侧脊髓丘脑束的损伤会导致左侧的痛觉、温度觉以及粗触觉的缺失，在病变平面1或2个脊髓节段以下。

Now, the spinothalamic tract is a bit different, because it crosses over to the opposite side of the spinal cord 1 or 2 spinal segments above, where the 1st order neurons enter.

脊髓丘脑束则有点不同，因为其第一级神经元群位置的关系，会在上升1或2个脊髓节段后交叉到对侧。
