[Essence of meridians based on neural electric field]

The physiological and pathological phenomenon along the running courses of meridians such as enrichment of small charged molecular, low-resistance, isotope migration, electromyography phenomenon, acoustical conductivity, thermal radiation, magnetic phenomenon and optical-electrical characteristics, etc. are explored in this article. And based on the above mentioned studies, it is concluded that as a physiological sensation along meridians, propagated sensation could only be the result of the reflection of nerve excitation. The direct stimulator of the neural electrical activities of the propagated sensation is the enrichment of charged small biological molecular at the corresponding site of the organism. The root cause of the enrichment is the unique electrophysiological mechanism and distribution discipline of the human nerve fiber, which formed an electric field of biological source for the concentration of the small molecular. Thus, it is concluded that the electric field along the running courses of meridians is an isopotential balanced line formed by multiple neural bioelectrical activities in different spaces closed to meridians.
