In other cases, people may not be able to keep their periaqueductal gray and other midbrain regions under control.
当研究人员在中脑导水管周围灰质内植入电极并且进行刺激时，这些小东西立刻开始奔逃并且不受控制地跳动。
When neuroscientists put electrodes into the periaqueductal gray region of rat brains and stimulated the neurons there, the creatures immediately started to run and jump uncontrollably.
不过，小脑扁桃体和中脑导水管周围灰质是大脑的两个古老原始的区域，可以追溯到亿万年前。
But the amygdala and the periaqueductal gray are ancient parts of the brain, dating back hundreds of millions of years.

Conclusion ETV is an effective method treating obstructive hydrocephalus caused by aqueduct stenosis and occupying lesions in posterior cranial fossa and midbrain.
应用神经束路追踪技术对大鼠孤束核（NTS）和最后区（AP）向中脑导水管周围灰质（PAG）的直接投射进行了观察。
The direct projections from the nucleus tractus solitarius (NTS) and area postrema (AP) to the periaqueductal gray (PAG) were investigated in the rat by using tract-tracing techniques.
