The report reviews recent publications of the authors (Masuda et al. 2007a and Masuda et al. 2007b) that investigated the effect of acute or subchronic exposure to radiofrequency electromagnetic fields on the cerebral microcirculation in rats using the monopole antenna that enabled local exposure to the brain. The report also shows the experimental details.

No noticeable changes in the cerebral microcirculatory parameters due to radiofrequency electromagnetic field exposure were found. For further details see Masuda et al. 2007a and Masuda et al. 2007b.
