Vagus Nerve Stimulation In Hypertensive Rats: Assessing Pathophysiology Using ECG And Pressure Data
… not all patients respond to current medications. Vagus nerve stimulation (VNS), which aims to restore autonomic balance, has emerged as a promising new treatment for this disease. In our lab, we conducted an experimental study aimed at assessing the safety and efficacy of chronic, continuously …

Simply (neuro-)stimulating: The effects of transcutaneous vagus nerve stimulation on phonological and lexical tone learning indexed by behavior and pupillometry
… neurostimulation. Transcutaneous auricular vagus nerve stimulation (taVNS) is a type of safe, non-invasive neurostimulation that delivers electrical current to the ear canal that has been shown to enhance cognition and learning (e.g., Jacobs et al., 2015). This dissertation investigated …

INVESTIGATIONS INTO THE EFFECTS OF ELECTRICAL STIMULATION OF THE VAGUS NERVE ON NOREPINEPHRINE IN THE CORTEX AND HIPPOCAMPUS OF EXPERIMENTALLY BRAIN INJURED AND UNINJURED RATS
The vagus nerve is the principal pathway by which autonomic sensory information is carried from the periphery to the CNS where it influences the activity of a numerous structures including the locus coeruleus. Electrical stimulation of the vagus nerve has been demonstrated to enhance performance in …

Behavioral Control of Seizures in Squirrel Monkeys (Saimiri sciureus)
… produced lesion of the nodosa ganglia of the vagus nerve, to condition the inhibition of seizures, and to theorize on sudden death. Procedures: eleven Squirrel monkeys were surgically implanted with depth electrodes. Electroencephalographic recordings were made and 38 days later lesions of the …

Action of drugs on the central nervous system with special reference to acetyl choline
1. Stimulation of the central end of the vagus and injection of acetyl choline in the ventricles of the brain have a similar effect on respiration, namely a marked depression of respiratory movements.

The effects of anticholinergic drugs on sea anemones
… He demonstrated that during stimulation of the vagus nerve leading to an excised frog’s heart (Figure 1) a chemical mediator that he called Vagus-substance was released which slowed the action of the heart. This chemical mediator entered a perfusion fluid consisting of isotonic sodium chloride …

Microdialysis to study the Gastrin-ECL cell Axis in the conscious rat
… back diffusion. We also examined whether the vagus and the sympathetic nervous system contributes to the food- and gastrin-evoked responses of ECL cells in situ. The results suggest that vagal activation does not stimulate histamine mobilization by a direct action on the ECL cells. Instead, …

Effects of Aquatic Therapy on Vagal Tone and Social Behaviors in Individuals with Autism Spectrum Disorder
… and cold exposure have been shown to increase vagus nerve activation (Mason et al.,2013; Presmanes et al., 2015; Yuan et al., 2001). Using a quasi-experimental block design, the present study evaluated the effect of aquatic therapy on vagal tone as well as behavior in participants with ASD …

Blood Pressure Regulation by the Endocannabinoid System in Conditions Associated with Hypertension
… for control of heart rate, an important index of vagus nerve function as well as general morbidity and mortality, is often impaired in conditions associated with hypertension. Restoration of baroreflex function is now recognized as a therapeutic strategy for prevention of cardiovascular diseases. …
