Our second brain is the brain in our gut or the ENS (the enteric nervous system).

我们的第二大脑是我们肠道或肠神经系统中的大脑。

Through this network of nerve connections, your big brain communicates stress to your enteric, or intestinal nervous system.

通过这个系统中神经纤维间的联系，你的大脑向你的肠道，或者说肠神经系统传递了压力的信号。

Isn't it called the enteric nervous system?

不是叫肠神经系统吗？

For those of you not au fait with physiology or anatomy, the enteric tract is the nervous system that regulates digestion.

对于那些不熟悉生理学或解剖学的人来说，肠道是调节消化的神经系统。

Research suggests that this network, known as the enteric nervous system, contains more than 100m neurons.

研究表明，这个被称为肠神经系统的网络包含超过 100m 个神经元。

Fischman: Those are the enteric neurons.

Fischman：这些是肠道神经元。

The enteric tracts of waterfowl such as ducks and geese are known to be the reservoirs for all known influenza A viruses.

已知鸭子和鹅等水禽的肠道是所有已知A型流感病毒的宿主。

When the vagus nerve is severed, the enteric nervous system is capable of organizing and initiating its own reflexes for digestion because it has such a complex collection of neurons.

当迷走神经被切断时，因其有如此复杂的神经元集合，肠道神经系统有能力组织和启动自己的消化反射。

In fact, there is a brain of sorts in your belly called the enteric nervous system which performs everything from sensing nutrients, measuring acids, and coordinating the immune system to defend your gut.

事实上，在你的肚子里有一个肠道神经系统，它可以感知营养、测量酸度、协调免疫系统来保护你的肠道。

In fact, the enteric nervous system, which is an extensive mesh-like network of neurons that controls your entire digestive tract from the esophagus to the anus, doesn't even require the brain at all.

事实上，肠道神经系统是一个由神经元组成的网状网络，控制着从食道到肛门的整个消化道，它甚至不需要大脑控制。
