Previous studies have revealed that the chemosensitive areas of the ventrolateral medullary surface participate in the central chemical regulation on respiration, but the exact location and the mechanism of the central chemoreception are still unknown.

延髓腹外侧表面的呼吸调节化学感受区参与中枢化学感受作用已有许多报道，但经电生理、神经解剖学等多方面的研究，至今尚未找到其化学感受的结构基础，因而其感受机制还不清楚。

The resultsdemonstrate:(1) GABA causes a decrease of blood pressure and heart rate by inhibiting sympathetic nerve in the part of the diencephalon, mesencephalon and medulla.

氨基丁酸在心血管活动中起着重要的调节作用。实验结果表明：(1)GABA可以作用于部分间脑、中脑和延髓而抑制交感神经，产生降低血压，减慢心率的作用。

For instance, the "banana" sign is caused by downward displacement of the cerebellum, with a resultant banana shape, and it also leads to effacement of the cisterna magna Fig. 10-19A-B and Fig.

例如，"香蕉"征是由小脑向下移位，造成了香蕉样的外形所引起，它还导致小脑延髓池的消失（图10-19A-B和图10-19-C）。

Arrhythmia probably related with G protein genetic in bulbus medullae expression disordering, which was very important to regulate arrhythmia by acupuncture Neiguan point.
