Support for the Theory: Proponents of PVT highlight its innovative framework for explaining the role of the vagus nerve in emotional regulation and social behavior. The theory has been widely adopted in trauma therapy, where practitioners use its concepts to help patients understand their physiological responses to stress and trauma.
The vagus nerve “has over 100,000 individual nerves in a bundle,” said neuroscientist Dr. Bashar Badran, associate professor of psychiatry and director of the Neuro-X Lab at the Medical ...
Excessive activation of the vagal nerve during emotional stress, which is a parasympathetic overcompensation for a strong sympathetic nervous system response associated with stress, can also cause vasovagal syncope due to a sudden drop in cardiac output, causing cerebral hypoperfusion. Vasovagal syncope affects young children and women more ...
To ease back into a calm state, you can try vagus nerve exercises like humming and breathwork. But Cain has a four-step plan to reprogram the mind and body. But Cain has a four-step plan to ...
Vagal tone is activity of the vagus nerve (the 10th cranial nerve) and a fundamental component of the parasympathetic branch of the autonomic nervous system. This branch of the nervous system is not under conscious control and is largely responsible for the regulation of several body compartments at rest.
“But your gut is connected to the central nervous system, largely via the vagus nerve. With that vagus nerve integration, it speeds up your bowel or slows it down and kind of sends extra signals ...
Cannon examined research on dogs performed by Sherrington, who separated the spinal cord and vagus nerves from all connections in the rest of the body, and found that the expression of emotion did not change, suggesting that the viscera do not have an observable impact on certain emotional behavior in dogs.

Vagus nerve stimulation (VNS) uses an implanted electrode and generator to deliver electrical pulses to the vagus nerve, one of the primary nerves emanating from the brain. It is an approved therapy for treatment-resistant depression in the EU and US and is sometimes used as an adjunct to existing antidepressant treatment.
