| Research Abstract |
The present study examined the neural mechanisms underlying the improvement of blood flow in the masseter muscle evoked by vagal afferent stimulation. Our results indicate that cervical vagus nerve stimulation elicits the increase of blood flow in the rat masseter muscle mediated by vagal-parasympathetic reflex vasodilatation, and suggest that nucleus of the solitary tract play an important role in the blood flow increase in the jaw muscles.
