The paper deals with experiments in a young patient who suffered from nerve deafness. Whenever the propagated sensation along channels (PSC) arrived at the left anterior auricular region, involuntary contraction of the mentioned muscles occurred. Therefore, during acupuncture a particular channel tract might be plotted out on the "body surface" (peripheral part) by means of blocking PSC with EMG as a responsive indication. EMG was led from zygomatic region by a pair of surface electrodes and recorded with a polyphysiograph. As PSC arrived at the preauricular region, intensive EMG could be evoked. There was a direct relation between EMG and PSC. With a series of control observation, it was demonstrated that EMG, as mentioned above, was really a particularly evoked response to PSC.
Mechanical compression had striking influence on PSC, which could be blocked when pressure was applied on its course and concomitantly EMG of the anterior auricular muscles disappeared. Whereas mechanical compression applied on either side or on the other part of the body, manifested no influence on PSC and EMG. Therefore, a series of blocking points could be found out by means of BPSC, when EMG was employed as an indication of response of acupuncture. For example, when "Quangming" was punctured and pressure applied on one of the following 14 points: Yanglingquan, Fengshi, Huantiao, Jingmen, Riyue, Jianjing, Fengchi, Shuaigu etc, the response of preauricular EMG could disappear immediately, but no influence occurred when mechanical compression applied on the control point apart from the channel or on other part of the body. Thus, a track could be plotted out by connecting these 14 blocked points (actually an unbroken line joined point by point). This track did not only bend forward and backward twice at the hypochondrium but also arrived at the preauricular region from the post auricular area, and its course was the same as the Gall Bladder Channel. In the same way, a track which coincided with the Sanjiao Channel could be mapped out on the "body surface" during puncturing of Waiguan point. The course of track might be presented steadily under repeated experiments. The evidence demonstrated that a particular channel track actually appeared over the "body surface" during acupuncture. Its course coincided with the path of PSC and was approximately in keeping with the course of channels described in books of Chinese medicine. Therefore, its existence was independent of subjective will of the subject. It revealed that PSC was not a simple phenomenon of sensation but a reflection of a certain process proceeding over "the body surface" during puncture.
