The researchers , writing in the online faseb journal , said that theobromine worked by suppressing vagus nerve activity , which is responsible for causing coughing 从事该研究的彼得巴内斯教授认为，此发现有望改进现在普遍采用的止咳方法。
Effects and significance of electrical stimulation of the vagus nerve on plasma levels of nitric oxide and endothelin in rats after intestinal ischemia reperfusion injury 电刺激迷走神经对肠缺血再灌注大鼠血浆一氧化氮和内皮素水平的影响及其意义
Pain , such as that caused by a cramp or choking , sends a signal to the vagus nerve , which in turns signals the heart , slowing it down so much that the person faints 抽搐或者窒息引起的疼痛会向迷走神经传送信息，然后这种信息又会传到心脏，导致心跳速度减慢，这样就会引起昏厥。
Result : the c3 to c7 , intervertebral discs , spinal cord , cervical nerves , vertebral artery , longus colli , larynx ( trachea ) , pharynx ( esophagus ) , common carotid artery ( internal and external carotid artery ) , internal jugular vein , vagus nerve and sternocleidomastoid were successfully reconstructed and displayed 结果：成功重建并立体显示第3 ~ 7颈椎、椎间盘、脊髓、颈神经、椎动脉、颈长肌、喉（气管） 、咽（食管） 、颈总动脉（颈内、外动脉） 、颈内静脉、迷走神经和胸锁乳突肌等解剖结构的位置关系，建立了颈前入路相关结构的三维可视化模型。
The main results as follows results from sinoatrial node in vivo 1 、 under bilateral vagi intact condition the value of hf ( high frequency power ) component , lf ( low frequency power ) component and apen value of ibis was the highest , but the lf / hf ratio was the lowest ; unilateral vagotomy decreased apen value of ibis , right vagotomy increased lf / hf ratio but left vagotomy did not 05 ） 。在离体窦房结还记录到自发轻度不规则放电，自发不规则放电使窦房结放电间期近似嫡从对照时的0二8土0 09 （ n 6 ）升高到不规则放电时的0
