- The vagus nerve connects the brain with the major organ systems of the body. It links mental and physical processes. It is the means by which the mind and body are physiologically inseparable; signals that affect one directly affect the other, although they find expression in different ways.

The vagus nerve is a sort of polymath of the parasympathetic nervous system, getting involved in everything from breathing, heart rate, swallowing, sneezing, digestion, appetite, immune responses and even orgasm. The vagus nerve’s wide-ranging skill set comes from having a diverse array of neuron cell types at its disposal.

Our nervous system is a complex structure that gathers information from all over our body and coordinates activity. There are two main parts of the nervous system: the central nervous system and the peripheral nervous system.
Our autonomic nervous system is complex and always busy. In addition to running important functions in our bodies, our autonomic nervous system is also helping us to scan, interpret, and respond to danger cues. There are two separate systems at work within our autonomic nervous system that help us read and respond to danger cues: 1. Sympathetic ner...
One nerve is of particular interest to Dr. Stephen Porges, Ph.D. Dr. Porges is a distinguished university lecturer, scientist, and developer of what is referred to as The Polyvagal Theory. The vagus nerve is the tenth cranial nerve, a very long and wandering nerve that begins at the medulla oblongata, a part of the brain located in the lower part o...
From the time we are born, we are intuitively scanning our environment for cues of safety and danger. A baby responds to the safe feelings of closeness with their parent or caregiver. Likewise, a baby will respond to cues that are perceived as scary or dangerous, like a stranger, a scary noise, or a lack of response from their caregiver. We scan fo...
In polyvagal theory, Dr. Porges describes the process in which our neural circuits read cues of danger in our environment as neuroception. Through this process of neuroception, we are experiencing the world in a way in which we are involuntarily scanning situations and people to determine if they are safe or dangerous. As part of our autonomic nerv...
Within his polyvagal theory, Porges describes the three evolutionary stages involved in the development of our autonomic nervous system. Rather than simply suggesting that there is a balance between our sympathetic and parasympathetic nervous systems, Porges describes a hierarchy of responses built into our autonomic nervous system. 1. Immobilizati...
When someone has experienced trauma, particularly in experiences where they were left immobilized, their ability to scan their environment for danger cues can become skewed. Of course, our body's goal is to prevent a terrifying moment like it again, so it will do whatever it needs to to protect us. When our body picks up a cue within an interaction...
As humans, we are constantly scanning the environment around us for safety and danger. And, according to polyvagal theory, the way our nervous system perceives threats impacts how our brain and body will respond to the situation. If you feel like you are experiencing excess immobilization, or are seeing danger cues more often than you should, it ma...
Oct 6, 2024 · The vagus nerve runs from the brain through the face and thorax to the abdomen. It is a mixed nerve that contains parasympathetic fibers and has the most extensive distribution of the cranial nerves. Learn more about the vague nerve in this article.

1 day ago · The vagus nerve is the 10th cranial nerve (CN X). It is a functionally diverse nerve, offering many different modalities of innervation. Due to its widespread functions, vagus nerve pathology is involved in a vast variety of clinical cases.
