Effects of Transcutaneous Auricular Vagal Nerve Stimulation on Chronic Constipation: A Multicenter, Randomized Controlled Study

United European Gastroenterology Journal, Volume 13, Issue 8, Page 1550-1559, October 2025.
ABSTRACT Objective The objective of this study was to investigate the efficacy of transcutaneous auricular vagal nerve stimulation (taVNS) in adult patients with chronic constipation. Design Consecutive patients who met the Rome IV criteria for chronic constipation were enrolled and randomly assigned to either the taVNS group or the sham‐taVNS group ...

The Future of Non‐Invasive Brain Stimulation in Sleep Medicine

Journal of Sleep Research, Volume 34, Issue 5, October 2025.
ABSTRACT Non‐invasive brain stimulation (NIBS) methods carry particular appeal as non‐pharmacological approaches to inducing or improving sleep. However, intense research efforts to use transcranial magnetic stimulation (TMS) and electrical stimulation (tES) for sleep modulation have not yet delivered evidence‐based NIBS treatments in sleep medicine ...

Pancreatic Islet Cell Hormones: Secretion, Function, and Diabetes Therapy

MedComm, Volume 6, Issue 9, September 2025.
The pancreatic islets, composed of α, β, δ, ε, and PP cells, play a central role in maintaining glucose homeostasis. This review examines the mechanisms of islet hormone secretion and their functional crosstalk networks, alongside the pathophysiology of diabetes driven by hormonal dysregulation.

The Effect of Transcutaneous Auricular Vagal Nerve Stimulation (taVNS) on P3 Event-Related Potentials during a Bayesian Oddball Task

Brain Sciences, 2020
Transcutaneous auricular Vagal Nerve Stimulation (taVNS) is a non-invasive brain stimulation technique associated with possible modulation of norepinephrinergic (NE) activity. NE is suspected to contribute to generation of the P3 event-related potential.

Effects of taVNS on physiological responses and cognitive performance during a mental stressor. [PDF]

Cogn Affect Behav Neurosci
Abstract Transcutaneous auricular vagus nerve stimulation (taVNS) affects autonomic function and enhances cognitive performance by increasing vagal activation and central noradrenergic activity. Nevertheless, the impact of taVNS on acute mental stress remains largely unexplored.

Learning from missteps: Potential of transcranial electrical stimulation in neuropsychological rehabilitation

Journal of Neuropsychology, Volume 19, Issue 3, Page 655-681, September 2025.
Abstract Transcranial electrical stimulation (tES) holds promise for neuropsychological rehabilitation by leveraging the brain's inherent plasticity to enhance cognitive and motor functions. However, early results have been variable due to oversimplified approaches.
