Gaber et al., 2004). Therefore, simultaneous investigation of several parameters is helpful to assess
the effects of RF–EMF exposures on the microcirculation.
The closed cranial window (CCW) method is one of the useful techniques to evaluate the cere-
bral microcirculatory parameters in experimental animals in vivo (Yuan et al., 2003; Gaber et al.,
2004; Masuda et al., 2007a–c, 2009, 2011). This method allows for direct observation of pial micro-
vasculature and several blood cells via a transparent glass window implanted on the parietal region
of the brain. To investigate the possible effects of the exposure to RF–EMF on cerebral microcir-
culation including several parameters mentioned earl
