Human prefrontal cortical response to the meditative state: a spectroscopy study.
The International journal of neuroscience July 2010 Richard W F Cheng, Donald S Borrett, Weyland Cheng et al.
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...
