Wake-promoting effects of vagus nerve stimulation after traumatic brain injury: upregulation of orexin-A and orexin receptor type 1 expression in the prefrontal cortex

Neural Regeneration Research, 2018
Orexins, produced in the lateral hypothalamus, are important neuropeptides that participate in the sleep/wake cycle, and their expression coincides with the projection area of the vagus nerve in the brain.

Vagus nerve stimulation primes platelets and reduces bleeding in hemophilia A male mice

Nature Communications, 2023
Deficiency of coagulation factor VIII in hemophilia A disrupts clotting and prolongs bleeding. While the current mainstay of therapy is infusion of factor VIII concentrates, inhibitor antibodies often render these ineffective.

Selective stimulation of the ferret abdominal vagus nerve with multi-contact nerve cuff electrodes

Scientific Reports, 2021
Dysfunction and diseases of the gastrointestinal (GI) tract are a major driver of medical care. The vagus nerve innervates and controls multiple organs of the GI tract and vagus nerve stimulation (VNS) could provide a means for affecting GI function and ...

Short-pulsed micro-magnetic stimulation of the vagus nerve

Frontiers in Physiology, 2022
Vagus nerve stimulation (VNS) is commonly used to treat drug-resistant epilepsy and depression. The therapeutic effect of VNS depends on stimulating the afferent vagal fibers.

Mortality and suicide risk in treatment-resistant depression: an observational study of the long-term impact of intervention.

PLoS ONE, 2012
Major depressive disorder is a common global disease that causes a significant societal burden. Most interventional studies of depression provide a limited assessment of the interventions on mortality and suicide risks.

Transcutaneous auricular vagus nerve stimulation improves dysautonomia, post-traumatic stress disorder and cognitive impairment in long covid patients: a pilot study

Scientific Reports
Long COVID is frequently associated with persistent autonomic dysfunction, cognitive impairment, and psychological distress, reflecting sustained neuroimmune and autonomic dysregulation. Effective disease-modifying therapies remain scarce.
