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 …

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. …

Role of the dorsomedial and ventrolateral medulla in the regulation of pain sensitivity in the endotoxemic organism
… the physiological and morphological effects of vagus nerve transection to the chemical destruction of its central projections. Subdiaphragmatic vagotomy disturbed nociception and body temperature regulation during endotoxemia. Micro-injections of glutamate or vanilloid receptor agonists in toxic …

Neuromodulation in Experimetal Animal Models of Epilepsy
… treatment strategies like epilepsy surgery, vagus nerve stimulation and deep brain stimulation. Besides the ongoing research on the efficacy of anti-epileptic treatments in suppressing seizures (anti-seizure effect), we want to seek for therapies that can lead to plastic changes in the …

Translational Modeling of Non-Invasive Electrical Stimulation
… models. Multi-scale models of transcutaneous vagus nerve stimulation (tVNS) were developed by coupling image-derived volume conduction models with physiological compartment modeling. The impact of local tissue inhomogeneities on fiber activation were considered.</p>

Naᵥ1.8+ Visceral Afferent Neurons: Roles in Metabolism and Inflammation
… inflammation. The sensory component of the vagus nerve has long been considered the main neural relay by which nutritional signals from the gut reach brain sites maintaining homeostasis. To study the function of this neuronal population, we generated a genetic mouse model with specific …

The effects of anticholinergic drugs on sea anemones
The first proof of the chemical mediation of nerve impulses by the peripheral release of specific chemicals was made by Loewi (1921). 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 …

Studies on the role of the autonomic nervous system in airway hyperreactivity.
… responses to applied ACh and stimulation of the vagus nerve in untreated tissues, indicating significant VDC involvement in the production of spontaneous and evoked tone. The calmodulin antagonist, trifluoperazine (TFP), also reduced responses to applied ACh and vagal stimulation in normal …

Examining the neurovisceral integration model through fNIRS
… with respiratory sinus arrhythmia (RSA), as the vagus nerve is part of this feedback system. While the NVM has been examined through neural imaging and RSA, only a few studies have examined these measures simultaneously during the neuroimaging procedure. Furthermore, these studies were done at …

Optimizing the neural response to electrical stimulation and exploring new applications of neurostimulation
… the potent, reversible effects of DBS.^ Left vagus nerve stimulation (VNS) is approved for treating epilepsy and depression. However, the standard method of determining stimulus parameters is imprecise, and the patient responses are highly variable. I developed a method of designing custom …
