So that means that each facial nerve contains motor information for the lower face coming from the contralateral motor cortex, and motor information for the upper face coming from both motor cortices.

也就说，每条面神经包含两种运动信号：1.控制下半脸的运动信号，来自对侧运动皮；2.控制上半脸的运动信号，来自双侧运动皮。

We check to see if it's back in place before x-rays by seeing if that arm goes up to the contralateral shoulder, that is the opposite shoulder.

我们检查它否在 x 光前恢复原位，通过观察手臂否能碰到另一侧的肩膀，也就对侧肩膀。

The vision is lost in halves that are contralateral to the posterior cerebral artery that is affected.

视野缺失会发生在受影响的大脑后动脉的对侧。

Now, normally damage to brain tissue results in weakness on the contralateral side, so, the Kernohan's notch causes a false localizing sign.

通常情况下，脑部成的肌肉无力发生在占位对侧，所以，Kernohan切迹会导致假性局灶征象。

This causes paralysis of only the lower half of the face on the contralateral side as the lesion, since the upper half of the face is still receiving some information from the ipsilateral motor cortex.

这类病只会导致对侧下半脸瘫痪，因为上半脸仍然能接收一些来自同侧运动皮的信号。

And if a, quote, healthy control wiggled their finger, you would see the contralateral motor cortex light up like in a textbook, like normal stuff.

如果一个所谓的健康对照者轻轻晃动手指，你就会看到对侧运动皮层像教科书里描述的那样被激活，也就正常的反应。

We need just enough connection to pass essential information between the hemispheres and enough connection to enable them to inhibit the contralateral hemisphere.

我们需要足够的接来在两个脑半球之间传递重要信息，并且有足够的接来使它们能够抑制对侧的脑半球。

In never smokers with breast cancer, postmastectomy radiotherapy is associated with an almost twofold increase in lung cancer risk in the ipsilateral but not the contralateral lung.

对于从不吸烟的乳腺癌患者，乳房切除术后放疗与同侧肺癌风险几乎增加两倍相关， 但与对侧肺癌风险无关。
