Spontaneous EEGs recorded with 12 channels (International 10-20 system) on the scalp were analyzed by statistical brain topographic mapping (t-test and correlation coefficient topographic mappings) to reveal changes of the electrical activity in the brain during Qi Gong state. The control subjects and two groups of masters and beginners in accordance with the time and the skilled degree practising Qi Gong were compared. The changes of EEGs of the Qi Gong masters during the Qi Gong state were clearly different from those recorded during the resting state with closed eyes. The EEG alpha activity occurred predominantly in the anterior half, and occurred silently in the posterior half of the brain during Qi Gong state. The peak frequency of EEG alpha rhythm during Qi Gong state was slower than resting state without practicing Qi Gong. The results of the t-test and correlation coefficient topographic mappings showed this finding quantitatively and statistically significant. The changes in EEG between resting and Qi Gong state for Qi Gong masters appear to be opposite. This findings indicates that Qi Gong state is a special and unusual state and this state is not an inherent state existing in each person. The occurrence of this phenomenon of EEG depends on the duration and the skilled degree of the practising Qi Gong.
通过统计脑地形图（t检验和相关系数地形图）分析头皮上用12个通道（国际10-20系统）记录的自发脑电图，以揭示气功状态下大脑电活动的变化。将对照组受试者与根据练习气功的时间和熟练程度划分的两组气功大师和初学者进行比较。气功大师在气功状态下的脑电图变化与闭眼静息状态下记录的脑电图变化明显不同。气功状态下，脑电图α活动主要出现在大脑前半部分，后半部分则无活动。气功状态下脑电图α节律的峰值频率比不练气功的静息状态慢。t检验和相关系数地形图的结果在数量和统计学上显示了这一发现具有显著性。气功大师在静息状态和气功状态下脑电图的变化似乎相反。这一发现表明，气功状态是一种特殊且异常的状态，并非每个人都固有的状态。脑电图这种现象的出现取决于练习气功的时长和熟练程度。
