它的一项职能就是,发出信号告诉这些器官,在人体处于平静和安全的时候减缓工作步伐。
How effectively the vagus nerve is working can be tracked by monitoring someone s heartrate as he breathes in and out.
你可以通过监测一个人呼吸时的心率来有效地追踪迷走神经的工作过程。
Healthy vagal function is reflected in a subtle increase in heart rate while breathing in and asubtle decrease while breathing out.
如果迷走神经工作正常的话,你可以从人体吸进空气时心率的不明显增加上看出来,同样,当人体呼出空气时心率也会有微弱的减少。
The difference yields an index of vagal tone, and the value of this index is known to beconnected with health.
如果迷走神经处于不健康状态时,会产生不同的迷走张力指数。
Low values are, for example, linked to inflammation and heart attacks.
众所周知,这个指数值与健康密切相关。比如,指数值低的话,就可能说明有炎症,及心脏病了。
What particularly interested Dr Fredrickson and Dr Kok was recent work that showedsomething else about the vagal-tone index:
特别有趣的是,弗雷德里克松教授和考克教授最近研究也显示了与迷走神经张力指数有关的其它东西。
