| 内容記述 | Many studies have shown a power increase of alpha activity and sometimes a high-amplitude theta rhythm over the frontal labes during meditation. But few studies have discussed the related brain areas. In this paper, studied qigong meditation by emplying a newly developed technique, optical topography to identify cortical areas specifically involved in the meditation state. As comparison, EEG results on the same task are also presented. Compared with the control state, our EEG analysisi results showed statistically significant increases (p<0.001) of alpha powere in Fp1 and O1 areas, whil statistically significant increases (p<0.001) of the theta power were found in Fz, C3, C4, T5 and T6 areas. In the analysisi of optical topography, the results varried considerably in djfferent regions. In the frontal areas, with the progression of the qigong meditation task, after decreasing for some time, oxygenated hemoglobin (HbO2) and toal hemoglobin (tHb) in creased together. While in the parietal-occipital areas, both of them decreased continuously. On the other hand, deoxygenated paruetal- occipital areas, both of them decreased continuously. On the other hand, deoxygenated hemoglobin (deoxy-Hb) increased slightly during the qigong meditation state, then declined gradually to the original level during the control state in the frontal areas, but remained constant employing near-infrared spectroscopy suggested that "revival after infibittion of th frontal lobes" could be one of ;the characteristics of the characteristics of the brain activity during qigong meditation. | |||||
