Since 1981 the author has observed and analyzed channel phenomenon in 'Zheng Qi Yong Xin Fa' (Chinese characters) exercisers at Zhou Tian Yong Xin (Chinese characters) stage and its several measurements as follows:
1. Character and regulation of PSC in qigong condition.
In addition to have characteristics of acupuncture inducing PSC mainly appear the PSC is qigong condition has its spontaneous total and regular quality.
(1). with definite start-stop point and moving line;
(2). with ceasing and strong-feeling point of the sense-conduct line (all are point); with two-direction sense-conduct phenomenon;
(3). sense-conduct lines, in addition to look like thin line basically, there are many types too;
(4). sense-conduct velocity is lower;
(5). sense-conduct strength is different in different men;
(6). sense-conduct have quality of tending to pathological area;
(7). 14 channels (dominant) sense-conduct all (start) from Ren-Dumai channel;
(8). many appear rhythmic during certain stage;
(9). spontaneous appear and disappear by itself only in certain stage during qigong condition, generally, no subjective methods to control its progress course;
(10). accompanied by such phenomenon as local limb movement spontaneously and feeling by oneself body toward back, slope, heavy, floating, increase, decrease and etc.
2. Sensation physiology and psychology basis of channel phenomenon in qigong condition;
(1). mainly are tactual sensation usually accompanied by temperature and pain sensation simultaneously;
(2). sense-conduct sensation is accompanied by phenomenon of muscle movement feeling and hallucination;
(3). channel susceptible men almost are skin sensitive ones;
(4). no hallucination appear in normal men and in exercisers no psychiatric disease;
(5). qigong feeling also express in some physiological specificity of receptor and synaptic transmission.
3. The exercisers with remarkable physiological change during PSC precess.
4. Several measurements during PSC process and its analysis;
(1). appearance of PSC is synchronous with the channel-point conduct electrical power and potential increase;
(2). points of skin temperature in heat-feeling area all are increasing. The measurements indirectly prove the relationship between occurrence of PSC in qigong condition and practical strength of 'channel spontaneous electric current,' also simultaneously manifest the growth and decline changes of sympathetic and parasympathetic nervous activities during this course.
The researches suggested above offer some basis for exploring the occurrence mechanism of PSC.
