Modulatory effects of transcutaneous auricular vagus nerve stimulation (taVNS) on attentional processes

General Psychiatry, 2023
Background The modulatory effect of transcutaneous auricular vagus nerve stimulation (taVNS) on attention has varied in previous studies. This inconsistency might be attributed to the combined influence of the modulation effect on the different ...

Stress and Tinnitus; Transcutaneous Auricular Vagal Nerve Stimulation Attenuates Tinnitus-Triggered Stress Reaction [PDF]

Frontiers in Psychology, 2020
IntroductionTinnitus can become a strong stressor for some individuals, leading to imbalance of the autonomous nervous system with reduction of parasympathetic activity. It can manifest itself as sleep disturbances, anxiety and even depression.

Assessing a Stimulator Modification for Simultaneous Noninvasive Auricular Vagus Nerve Stimulation and MRI. [PDF]

J Neuroimaging
ABSTRACT Background and Purpose The vagus nerve can be stimulated noninvasively at the ear using transcutaneous auricular vagus nerve stimulation (taVNS). Concurrent functional MRI (fMRI) permits study of taVNS‐induced changes in brain dynamics, a key requisite for precision neurostimulation. However, there is no standardized protocol for how to safely

Transcutaneous auricular vagus nerve stimulation may benefit from the addition of N-acetylcysteine to facilitate motor learning in infants of diabetic mothers failing oral feeds [PDF]

Frontiers in Human Neuroscience
ObjectiveThis study aims to determine if pretreating with enteral N-acetylcysteine (NAC) improves CNS oxidative stress and facilitates improvement in oromotor skills during transcutaneous auricular nerve stimulation (taVNS) paired with oral feedings in ...

The effect of transcutaneous auricular vagus nerve stimulation on cardiovascular function in subarachnoid hemorrhage patients: A randomized trial [PDF]

eLife
Background: Subarachnoid hemorrhage (SAH) is characterized by intense central inflammation, leading to substantial post-hemorrhagic complications such as vasospasm and delayed cerebral ischemia.

Electroencephalographic Patterns in taVNS: A Systematic Review

Biomedicines, 2022
Transcutaneous auricular vagus nerve stimulation (taVNS) is a newer delivery system using a non-invasive stimulation device placed at the ear. taVNS research is focused on clinical trials showing potential therapeutic benefits, however the neurophysiological effects of this stimulation on brain activity are still unclear. We propose a systematic review

Feasibility and Safety of a Single-Session of Transcutaneous Cervical Magnetic Stimulation, taVNS, and iTBS on Heart Rate Variability, Safety, and Pain Modulation. [PDF]

Eur J Neurosci
tCMS showed the most favorable safety profile, with fewer adverse effects than taVNS and iTBS. No significant differences were observed in heart rate variability or pain modulation between the stimulation groups and the Sham stimulation group. ABSTRACT The autonomic nervous system (ANS) plays a crucial role in maintaining homeostasis, and its ...

30 Hz Transcutaneous Auricular Vagus Nerve Stimulation Alleviates Abdominal Pain by Modulating EEG Activity in the α Frequency Band of the Brain. [PDF]

CNS Neurosci Ther
Persistent abdominal pain (PAP) is linked to reduced prefrontal alpha oscillations, correlating with pain severity. Our study found that 30 Hz transcutaneous auricular vagus nerve stimulation (taVNS) effectively enhanced these alpha rhythms in key prefrontal regions and was selected for intervention.

Phasic, Event-Related Transcutaneous Auricular Vagus Nerve Stimulation Modifies Behavioral, Pupillary, and Low-Frequency Oscillatory Power Responses [PDF]

, 2023
Transcutaneous auricular vagus nerve stimulation (taVNS) has been proposed to activate the locus ceruleus-noradrenaline (LC-NA) system. However, previous studies failed to find consistent modulatory effects of taVNS on LC-NA biomarkers.

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 ...
