One of the longest nerves in the body is known as the vagus nerve (VN). The VN is the 10th pair of cranial nerves that originates at the brain stem in the medulla oblongata. This nerve is part of the parasympathetic nervous system, which is a part of the ANS. Research suggests ear acupuncture can activate the VN.

Mark Reinhard, an acupuncturist with more than 30 years of experience, practices in Kent, Wash. He has taught electroacupuncture at the Northwest Institute of Acupuncture and Oriental Medicine (his alma mater), the Seattle Institute of Acupuncture and Oriental Medicine, and Bastyr University. Mark is also an electrical engineer (Georgia Tech, 1981 graduate), which he says is particularly relevant since many of acupuncture's effects are bioelectrical in nature. He is currently designing and building various electroacupuncture machines, and has been using frequency-specific microcurrent in practice for the past several years.
