Trans auricular vagus nerve stimulation (taVNS) is an innovative non-invasive technique to modulate brain function and address neuropsychiatric disorders. It delivers electrical stimulation to the auricular branch of the vagus nerve via the outer ear. Research highlights its potential benefits, including increased heart rate variability and reduced sympathetic nerve activity. Notably, stimulation is preferred on the left ear to minimize cardiac-related side effects. Comparatively, experiences with cranioelectrical stimulation (CES) indicate rapid stress relief, leading to discussions about the comparative ease and effectiveness of taVNS in similar applications.
Trans auricular vagus nerve stimulation (taVNS) is one of the less invasive approaches to modulate brain function in neuropsychiatric and degenerative disorders.
TaVNS is a non-invasive brain stimulation technique that involves the delivery of electrical stimulation to the auricular branch of the vagus nerve, accessible through the outer ear.
The predominant concern with right-sided or bilateral cervical VNS is its potential to influence cardiac function since the right vagus nerve provides more substantial innervation to the heart.
TaVNS increased heart rate variability and reduced sympathetic nerve outflow, with effects noted best at the beginning of stimulation.
