Something is happening to the signals in his midbrain.

他脑的讯号出了些情况。

I've never been that deep in the midbrain before.

我从未操作过这么深入脑的测试。

The brain stem houses the lower nerve centers (consisting of midbrain, pons, and medulla).

脑干容纳低级神经(脑、脑桥和延髓组成)。

Alcohol also stimulates a small group of neurons that extends from the midbrain to the nucleus accumbens, a region important for motivation.

酒精也会对一小部分神经细胞有激，并从脑持续到伏隔核区域，而伏隔核在奖赏和快乐等感官体验具有重要作用。

In contrast, neurons in a section of the midbrain called the substantia nigra are in charge of initiating movement and other motor function.

相形之下，脑有一个区域叫做黑质，黑质神经元负责运动的设计启动以及其他运动功能。

We usually refer to the substantia nigra as if it’s in a single location, but there are actually two of these regions in the brain, one on each side of the midbrain.

“黑质”听起来像是指某个具体的位置，但实际上是指大脑的两个区域，分别位于脑两侧。

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，它通过脑的皮质脊髓束向上运动神经元发送运动信号，先交叉至对侧延髓，然后继续下行。
