In recent years, multi-channel near-infrared spectroscopy (NIRS) is being used as a new brain imaging technology. Some studies on Qigong have been done by NIRS. But most of them were reports for just one example. In this study, by seven Qigong experts and fourteen normal controllers, optical topography was used to study blood volume change of the cerebral cortex in frontal and frontal-parietal areas during Qigong. Analysis on the right frontal (Fp2) and cardiac variability of R-R interval was compared with the control task. The experts could be divided into two groups: (1) the blood volume increased (p<0.05) while the sympathetic nerve system predominated (p<0.05) which showed the experts emitted Qi by concentrating more strongly and (2) the blood volume decreased (p<0.01) while the parasympathetic nerve system predominated (p<0.05) which showed the experts emitted Qi just by relaxing in the Qi-emission task. Two groups of experts also showed increase (p<0.05) or decrease (p<0.01) during Qi-emission task compared to the normal controllers.
