vagus nerve

Brain-gut neural highway

The vagus nerve is the longest cranial nerve, running from the brainstem through the neck and chest to the abdomen.

It regulates heart rate, digestion, and other involuntary functions, forming a key pathway between brain and body.

The vagus nerve has gained popular attention for its role in stress response—stimulating it through breathing exercises or cold exposure supposedly promotes calm.
