Although we refer to the vagus nerve as singular, it’s actually a pair of nerves that emerge from the left and right side of the medulla oblongata portion of the brain stem.

Where does the vagus nerve begin and end?
Vagus nerve branches in the thorax On the right side, it arises from the trunk of the vagus as it lies beside the trachea. On the left side, it originates from the recurrent laryngeal nerve only. These branches end in the deep part of the cardiac plexus.
How is the vagus nerve connected to the brain?
The device is usually placed under the skin of the chest, where a wire connects it to the left vagus nerve. Once the device is activated, it sends signals through the vagus nerve to your brainstem, transmitting information to your brain.
What is the vagus nerve and where is it located?
The vagus nerve carries an extensive range of signals from digestive system and organs to the brain and vice versa. It is the tenth cranial nerve, extending from its origin in the brainstem through the neck and the thorax down to the abdomen.
Can neck problems affect the vagus nerve?
While doctors usually discuss the vagus nerve in singular sense, there are two vagus nerves, one on each side of the neck and in combination they are referred to as the vagal nerves. This means that the degenerative damage in your neck can significantly impact the function of one or both vagus nerves.
What can trigger the vagus nerve?
The vagus nerve is connected to your vocal cords and the muscles at the back of your throat. Singing, humming, chanting and gargling can activate these muscles and stimulate your vagus nerve. And this has been shown to increase heart-rate variability and vagal tone (12).
Does the vagus nerve cause anxiety?
A low vagal tone means the vagus nerve isn’t functioning as it should. This may lead to a heightened stress response which becomes chronic, possibly resulting in depression, anxiety, gut issues and inflammation.
Can the vagus nerve cause headaches?
The vagus nerve acts as the brakes for the heart. So irritation of the nerve by surrounding muscles or bones can lead to inhibition of the nerve thus removing the brakes for heart rate, which means a faster heart. The nerve has also been implicated in headaches (7).
Does the vagus nerve affect the eyes?
It initiates in the core of the brain and travels to the depths of the gut. Along its travels, it affects eye movement, facial expressions, tone of voice, heart rate and heart rate variability, breathing, and the function of the spleen, liver, kidneys and intestines.
What calms the vagus nerve?
Slow, rhythmic, diaphragmatic breathing. Splashing cold water on your face, or taking a cold shower, stimulates the dive reflex, which is associated with stimulating the vagus nerve. You can also achieve the same effect by holding a ziplock bag filled with ice cubes against your face and holding your breath.
What doctor treats the vagus nerve?
A neurologist is an expert in diagnosing and treating problems of your brain, spinal cord and nerves, including these 8 neurological symptoms and disorders.
Can poor posture affect the vagus nerve?
When you slouch, inevitably your head goes forward. As this occurs you will affect a nerve called the Vagus Nerve, and it will not work effectively. The Vagus nerve acts to help counteract your adrenal system – your fight or flight system of the body.
Does vagus nerve damage show on MRI?
Distal vagal lesions occur as an isolated paralysis of the vagus nerve with no symptoms or signs referable to the oropharynx. Either computed tomography (CT) or magnetic resonance imaging can be used to diagnose proximal or distal lesions.
