The vagus nerve is one of the cranial nerves, meaning a nerve that is connected directly to the brain. Output nerve fibres control muscles responsible for swallowing, coughing and voice sounds. Input nerve fibres transmit sensations and electrical feedback from the heart, lung, stomach and upper bowel to the brain.bout 80% of the nerve fibres in the left vagus nerve are input fibres transmitting, from the body to the brain, and the output fibres have minimal heart connections, making the left vagus nerve a suitable wire into the brain.
