Figure 6: Near infrared spectroscopy parameters from a 28-year-old healthy male volunteer during laserneedlelß)stimulation<br />

with scheme A in Figure 5. Observe the relative increase ( + 1.5 p.mol) in oxyhemoglobin (O2Hb) and the<br />

simultaneous decrease (-0.9 p.mol) in desoxyhemoglobin (HHb) correlated to the initial value<br />

showed specific changes in blood flow velocity and<br />

regional cerebral oxygenation in our 22 healthy<br />

volunteers.<br />

<strong>Laser</strong>needle@ stimulation of points Yingxiang, Hegu<br />

and Pianli, which are connected to the olfactory system<br />

according to traditional Chinese medicine, lead to a<br />

significant change in blood flow velocity in the ACA.<br />

The ACA supplies major regions of the frontal and<br />

median area of the brain, including the olfactory cortex.<br />

At the same time, blood flow in the PCA remained<br />

nearly unchanged. In comparison, laserneedle@ stimulation<br />

of points Guangming, Taichong and Zhiyin,<br />

which are supposed to be connected to the optic<br />

system, showed a significant increase in blood flow<br />

velocity in the PCA, whereas flow in the ACA only<br />

changed irrelevantly3.<br />

Modern biomedical techniques such as multidirectional<br />

transcranial Doppler sonography, near-infrared<br />

spectroscopy or laser Doppler flowmetry combined with<br />

thermography are able to quantify the effects of<br />

laserneedle@ acupuncture objectively.<br />
