Inflammatory bowel disease (IBD) encompasses Crohn's disease (CD) and ulcerative colitis (UC), is a major health problem on a global scale and its treatment is unsatisfactory. We aimed to investigate the effects of transauricular vagal nerve stimulation (tVNS) on inflammation in rats with IBD induced by trinitrobenzene sulfonic acid (TNBS). A total of 36 adult female Sprague-Dawley rats were given TNBS, or vehicle, and tVNS, or sham, every other day for 30 min for 10 days.

Background: Invasive vagus nerve stimulation (iVNS) is approved for the treatment of major depressive disorder (MDD). The limited understanding of its underlying mechanisms, however, hinders stratification and the prediction of treatment response. Given the strong projections of the afferent vagal nucleus to brain regions involved in emotional processing, we tested whether acute transauricular VNS (taVNS) can improve emotional processing that is a core deficit in MDD.

Autism is a neurodevelopmental disorder with limited treatment alternatives and which incidence is increasing. Some research suggests that vagus nerve simulation might lead to the reduction of certain symptom. Therefore, we aimed to examine the effect of bilateral transcutaneous auricular vagus nerve stimulation (tVNS) on the inflammatory response in an adult valproic acid (VPA) induced mouse (C57BL6) model of autism for the first time.

Introduction: Conditioned pain modulation (CPM) is a quantitative estimation of the capacity for endogenous pain modulation. Reduced CPM enables chronic painful event development or exacerbates pre-existing pain symptoms. Emerging reports indicate that patients with trigeminal neuralgia (TN) have dysregulated endogenous pain modulation.
