Peripheral responses of autonomic nervous system (ANS) as skin electrodermal activity (EDA), vasoconstriction or dilatation and sudorimotoric effect are widely used in psychophysiological studies.
The aim of present experiment was to clarify, if the microcirculation varies in different sites on volar surface of distal phalanx of finger.
Eight volunteer adult subjects who claimed themselves as hand-mediated healers were examined. After cleansing the skin of the distal phalanx volar surface of left middle finger was covered by a dielectric film. The bioactive points (BAPs) were visualized by using negative and positive air plasma generator (ACU Vision-04, Coloyaro 2000 Ltd., Moscow, Russia). The electroluminescent points were marked with pencil on skin. The microcirculation of the fingertip was recorded in four points of luminescence and one control point in the non-luminescent area in the middle of the pad using ultrasound Doppler with working tip Ш 1.5 mm and frequency of 20 MHz (Minimax-Doppler-K, Minimax Ltd., St. Petersburg, Russia). The responses of volunteers to high-tension electromagnetic field impulses (1000 Hz, 8kV, 20 msec impulse duration) were tested by analyzing the gas discharge pattern (GD-image) around the right middle fingertip (CrownTV, Kirlionics International Ltd., St. Petersburg, Russia) before and during startle probes. The areas of these images were calculated (background 255, removing fragments up to 10 pixel). After the startle probe the blood microcirculation was recorded in same points as at beginning of the experiment.
During visualization BAPs appeared as cyclically luminescencing spots (diameter ~ 1mm) like an oval chain of beads in the volar rim of the distal fingerphalanx. The response of points to negative or positive air plasma administration and the level of their luminescence varied. No BAPs were detected in central control pad area, where the microcirculation was also recorded. Among volunteers studied there were different responses to electromagnetic field impulses, but a decreasing trend of GD response during startle probe prevailed. Energy emissions in GD was frequently registered during a self-imagination task. The blood microcirculation of the pad center showed a small increase after the startle probe and clearly more marked increase was registered in active BAPs in the volar rim of the distal phalanx.
In conclusion: the microcirculation and its variation at the specific bioactive points in the volar rim of fingertip have not been previously reported. It appears that people can with their will modify there their circulatory and emissive responses during a psychophysiological test.
