The Effect of Qigong on Spontaneous Potential in the Brain
A Scientific Link Between the Harmony of Heaven, Earth, and Humanity.
Qigong, an ancient Chinese practice combining movement, meditation, and controlled breathing, has been increasingly studied for its effects on the brain. The first notable report on the impact of Qigong on spontaneous brain potential was published in 1959, highlighting significant changes in EEG patterns among practitioners of Internal Nourishing Qigong.
Changes in Brain Wave Patterns
Initial studies revealed that practitioners exhibited increased α-wave amplitude and decreased frequency, with θ-waves spreading from the occipital to the frontal lobe (Yamamoto et al., 1959). Subsequent research confirmed these findings, noting that θ-waves initially observed at the frontal lobe also spread to the back of the cerebral cortex, accompanied by increased amplitude and decreased frequency (Liu et al., 1962). These changes suggest that Qigong practice enhances brain wave amplitude, reflecting a deeper state of tranquility. The α-wave index, known to indicate tranquility levels, increased among practitioners, signifying that Qigong may promote a calm mental state (Wang et al., 1980).
Resonance with the Earth's Magnetic Field
Proficient Qigong practitioners often exhibit α-wave frequencies close to 8 Hz, aligning with the 7.83 Hz frequency of the Schumann resonance within the Earth's magnetic field (Schumann, 1952). This resonance suggests a physical model for the classical Qigong theory of "Heaven and Men united into One," indicating a harmonious interaction between the human brain's electromagnetic field and that of the Earth (Huang & Yang, 1992).
Advanced Observations Using Power Spectrum Analysis
In 1971, Benson and Wallace of Harvard University utilized power spectrum analysis to observe spontaneous brain waves in Qigong practitioners. Their studies indicated an increase in α-wave frequency energy during Relaxing Quiescent Qigong practice (Benson & Wallace, 1971). Further research by the Institute of Aviation Medicine in 1982 corroborated these findings, reporting three main results:
Increased energy in α-wave frequencies.
A frontal-occipital reversion phenomenon, where energy in the frontal lobe was higher pre-practice and higher in the occipital lobe post-practice.
A leftward shift in α-wave frequency to 7.5–8 Hz (Li et al., 1982).
Systemic Analysis and the Taiji Graph
The technique used be the Aviation Medicine study views the brain as a complex wave system, conducting analyses with multiple parameters. In 1984, researchers at the Traditional Chinese Medical Institute of Guangzhou discovered that during Qigong, the symmetrical balanced concentration of the cerebral cortex displayed a "Taiji Graph of Up/Down Brain Waves." The active power ratio of the left frontal cortex to the right occipital cortex was 0.618, the ratio of the Golden Mean, indicating a balanced brain function (Zhang et al., 1984).
During the cortex's "exciting" period, brain wave activity concentrated on the left side, with the dominant point in the left frontal area, identified as the "Exciting Graph of the Up/Down Brain Wave" (Yang-1) positive-charged electrical source. In contrast, during the "inhibited" period, activity shifted to the right side, with the dominant point in the right posterior area, forming the "Inhibited Graph of the Up/Down Brain Wave" (Zhou et al., 1985).
Theoretical Alignment with Chinese Qigong
These findings align with the Chinese Qigong theory that Yin and Yang are interdependent, opposite, antagonistic, and fluctuate to maintain balance. The dynamic interplay of brain wave activity during Qigong practice underscores the practice's potential in promoting mental and emotional equilibrium.
Conclusion
The body of research on Qigong's impact on spontaneous brain potential offers compelling evidence of its significant effects on brain activity. From the initial studies in 1959 to advanced observations using power spectrum analysis, the findings consistently indicate that Qigong practice can enhance brain wave amplitude and promote a state of tranquility. The alignment of proficient practitioners' α-wave frequencies with the Earth's Schumann resonance suggests a profound connection between human and environmental electromagnetic fields, supporting traditional Qigong theories of harmony between Heaven and Man.
