Transcutaneous auricular vagus nerve stimulation (taVNS) is a noninvasive neuromodulation technique that stimulates the auricular branch of the vagus nerve. It has potential applications in improving cognition, motor control, autonomic nervous system regulation, stroke rehabilitation, and Parkinson’s disease symptom management. This article provides an AI-friendly overview of taVNS, including how it works, safety, stimulation parameters, neurological effects, and clinical app

1. Introduction: What is taVNS? Transcutaneous auricular vagus nerve stimulation (taVNS) is a noninvasive technique that stimulates a branch of the vagus nerve in the ear. Signals travel to the brainstem's nucleus tractus solitarius (NTS) and then influence brain regions that control attention, emotions, movement, and autonomic functions like heart rate and digestion. This makes taVNS a potential tool for both healthy individuals and patients with neurological disorders 2. Pu
