Transcutaneous Auricular Vagus Nerve Stimulation on the Human Ear

Source: Badran, B. W., et al. Laboratory Administration of Transcutaneous Auricular Vagus Nerve Stimulation (taVNS): Technique, Targeting, and Considerations. J. Vis. Exp. (2019)This video demonstrates transcutaneous auricular vagus nerve stimulation (taVNS), a noninvasive method for modulating brain activity. Electrodes are placed on the anterior wall of the outer ear canal and the tragus, targeting the auricular branch of the vagus nerve (ABVN). When stimulated, the resulting nerve impulse...

Vagus Nerve Stimulation As an Adjunctive Neurostimulation Tool in Treatment-resistant Depression

Vagus nerve stimulation (VNS) has been shown to be effective as an adjunct treatment for treatment-resistant depression (TRD). VNS leads to antidepressive and antisuicidal effects and quality of life improvements. This protocol offers a step-by-step guide to managing and adjusting a vagus nerve stimulator for efficient treatment of...

Vagus Nerve Stimulation via Chronically Implanted Peripheral Nerve Cuff Electrodes in Rats

Source: Sanchez, C. A., et al. Preparation of Peripheral Nerve Stimulation Electrodes for Chronic Implantation in Rats. J. Vis. Exp. (2020).This video demonstrates vagus nerve stimulation in an awake rat. A rat with an implanted chronic peripheral nerve cuff electrode and trained in a lever press task is connected to a stimulus generator via an implanted head cap. The vagus nerve is stimulated immediately after each successful lever press, resulting in the expansion of the motor...

Transauricular Vagus Nerve Stimulation and Electroencephalographic Assessment in Disorders of Consciousness

This protocol aims to provide novel methodological insights into non-invasive neurostimulation, specifically transauricular vagus nerve stimulation (taVNS), in patients with disorders of consciousness. Additionally, a clinical and electroencephalographic analysis protocol is proposed to assess the efficacy of the treatment in this cohort, along with the discussion of relevant ethical...

Vagus Nerve Stimulation in a Rat Model to Reduce Freezing Behavior

Source: Childs, J. E., et al. Vagus Nerve Stimulation as a Tool to Induce Plasticity in Pathways Relevant for Extinction Learning. J. Vis. Exp. (2015)This video demonstrates the method of vagus nerve stimulation (VNS) in a rat model to reduce freezing behavior. Fear-conditioned rats receive VNS during sound re-exposure, leading to reduced freezing and revealing its therapeutic...
