Key result
Qigong meditation links to increased prefrontal oxyhemoglobin and decreased deoxyhemoglobin compared to non-practitioners.
Why the study?
Does Qigong meditation alter prefrontal cortex hemodynamics in practitioners compared to non-practitioners?

Does Qigong meditation alter prefrontal cortex hemodynamics in practitioners compared to non-practitioners?
Qigong meditation significantly alters prefrontal cortex hemodynamics, suggesting increased prefrontal activation.
Hypothesis-generating for Qigong effects on prefrontal hemodynamics; prospective trials needed before clinical adoption.
The effect of Qigong meditation on the hemodynamics of the prefrontal cortex was investigated by spectroscopy with a single-wavelength probe (650 nm) and confirmed by standard near-infrared spectroscopy with a dual-wavelength probe. Deoxyhemoglobin changes were recorded with the single-wavelength probe over the left prefrontal cortex during meditation by Qigong practitioners, and non-practitioners instructed in the technique. Practitioners showed a significant decrease in deoxyhemoglobin levels suggesting an increase in prefrontal activation during meditation. The results were confirmed in a second set of experiments with the standard dual-wavelength probe, in which significant differences in the decrease in deoxyhemoglobin and increase in oxyhemoglobin concentrations were observed in practitioners as compared with non-practitioners. The study thus provides evidence that Qigong meditation has a significant effect on prefrontal activation.

Cheng et al. (2010) reported an observational. Qigong meditation vs. Non-practitioners instructed in the technique was evaluated on Hemodynamics of the prefrontal cortex (deoxyhemoglobin and oxyhemoglobin changes). Qigong meditation by practitioners resulted in a significant decrease in deoxyhemoglobin and increase in oxyhemoglobin in the prefrontal cortex compared to non-practitioners.
