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 />
