The initiation and progression of ischemic and hemorrhagic stroke are the result of a complex cascade of processes that determine both the extent of the lesion and long-term outcome. Several of these processes, including peripheral inflammation, neuroinflammation, and neuroplasticity are influenced by the activity of the afferent as well as efferent pathways of the vagus nerve. It was shown that vagus nerve stimulation significantly reduces the extent of stroke-induced lesion of brain parenchyma. However, the mechanisms of beneficial effect of increased vagal activity on pathological processes related to stroke remains largely unclear. The aim of this article is to describe the role of afferent and efferent vagal pathways in the mechanisms that influence the initiation of stroke as well as its detrimental effects.

The vagus nerve is a major component of the autonomic nervous system and plays a critical role in many body functions including for example, speech, swallowing, heart rate and respiratory control, gas...
The goal of this paper was to present the effects of the vagus nerve stimulation (VNS) on a blood pressure (BP) and heart rate (HR) in arterial hypertension patient.
Hepatic ischemia-reperfusion (HIR) injury is a complication of liver surgery. As much as 50% of hepatocytes undergo apoptosis within the first 24 h of reperfusion. The neurotransmitters of the vagus...

The goal of this study is to investigate the influence of transcutaneous vagus nerve stimulation 1. on the noradrenergic system in the brain and 2. on memory, in healthy volunteers. ...
The investigators would like to explore possibilities of selective vagus nerve stimulation in human subjects to control heart rate and arterial blood pressure.
Previous studies suggested that both robot-assisted rehabilitation and non-invasive vagus nerve stimulation can improve upper limb function in chronic stroke patients. Aim of present study...
An adjunctive treatment for PARTIAL EPILEPSY and refractory DEPRESSION that delivers electrical impulses to the brain via the VAGUS NERVE. A battery implanted under the skin supplies the energy.
The 10th cranial nerve. The vagus is a mixed nerve which contains somatic afferents (from skin in back of the ear and the external auditory meatus), visceral afferents (from the pharynx, larynx, thorax, and abdomen), parasympathetic efferents (to the thorax and abdomen), and efferents to striated muscle (of the larynx and pharynx).
The inferior (caudal) ganglion of the vagus (10th cranial) nerve. The unipolar nodose ganglion cells are sensory cells with central projections to the medulla and peripheral processes traveling in various branches of the vagus nerve.
The 12th cranial nerve. The hypoglossal nerve originates in the hypoglossal nucleus of the medulla and supplies motor innervation to all of the muscles of the tongue except the palatoglossus (which is supplied by the vagus). This nerve also contains proprioceptive afferents from the tongue muscles.
Diseases of the tenth cranial nerve, including brain stem lesions involving its nuclei (solitary, ambiguus, and dorsal motor), nerve fascicles, and intracranial and extracranial course. Clinical manifestations may include dysphagia, vocal cord weakness, and alterations of parasympathetic tone in the thorax and abdomen.
