Brain–Heart Interaction During Transcutaneous Auricular Vagus Nerve Stimulation [PDF]
Frontiers in Neuroscience, 2021 ObjectivesTranscutaneous auricular vagus nerve stimulation (taVNS) modulates brain activity and heart function. The induced parasympathetic predominance leads to an increase of heart rate variability (HRV). Knowledge on the corresponding cortical activation pattern is, however, scarce.

Auricular transcutaneous vagus nerve stimulation modulates the heart-evoked potential [PDF]
Brain Stimulation, 2022 There is active interest in biomarker discovery for transcutaneous auricular vagus nerve stimulation (taVNS). However, greater understanding of the neurobiological mechanisms is needed to identify candidate markers. Accumulating evidence suggests that taVNS influences activity in solitary and parabrachial nuclei, the primary brainstem relays for the ...

Neuro-cardiac coupling predicts transcutaneous auricular vagus nerve stimulation effects [PDF]
Brain Stimulation, 2021 Transcutaneous auricular Vagus Nerve Stimulation (taVNS) is a non-invasive neuromodulation technique that may constitute an effective treatment for a wide range of neurological, psychiatric, and medical conditions. One key challenge in taVNS research is the high interindividual response variability.

Auricular Transcutaneous Vagus Nerve Stimulation Acutely Modulates Brain Connectivity in Mice [PDF]
Frontiers in Cellular Neuroscience, 2021 Brain electrical stimulation techniques take advantage of the intrinsic plasticity of the nervous system, opening a wide range of therapeutic applications. Vagus nerve stimulation (VNS) is an approved adjuvant for drug-resistant epilepsy and depression.

Transcutaneous Auricular Vagus Nerve Stimulation Triggers Melatonin Secretion and Is Antidepressive in Zucker Diabetic Fatty Rats [PDF]
, 2014 Decreased circulating melatonin is implicated in depression. We recently found that Zucker diabetic fatty rats (ZDF, fa/fa) develop depression-like behaviors and that transcutaneous auricular vagus nerve stimulation (taVNS) is antidepressive in ZDF rats.

The anatomical basis for transcutaneous auricular vagus nerve stimulation [PDF]
Journal of Anatomy, 2019 AbstractThe array of end organ innervations of the vagus nerve, coupled with increased basic science evidence, has led to vagus nerve stimulation (VNS) being explored as a management option in a number of clinical disorders, such as heart failure, migraine and inflammatory bowel disease.

Transcutaneous Auricular Vagus Nerve Stimulation Facilitates Cortical Arousal and Alertness
International Journal of Environmental Research and Public Health, 2023 Transcutaneous auricular vagus nerve stimulation (taVNS) is a promising noninvasive technique with potential beneficial effects on human emotion and cognition, including cortical arousal and alertness. However, it remains unclear how taVNS could improve cortical arousal and alertness, which are crucial for consciousness and daily task performance. Here,

Transcutaneous vagus nerve stimulation does not affect verbal memory performance in healthy volunteers [PDF]
, 2020 Introduction: Invasive vagus nerve stimulation (VNS) improves word recognition memory in patients with epilepsy. Recent studies with transcutaneous VNS (tVNS) have also shown positive effects on various subdomains of cognitive functioning in healthy ...

Transcutaneous auricular vagus nerve stimulation augments postprandial inhibition of ghrelin
Physiological Reports, 2022 Vagus nerve stimulation (VNS) facilitates weight loss in animals and patients treated with VNS for depression or epilepsy. Likewise, chronic transcutaneous auricular VNS (taVNS) reduces weight gain and improves glucose tolerance in Zucker diabetic fatty rats. If these metabolic effects of taVNS observed in rats translate to humans is unknown. Therefore,
