In bionet.neuroscience Allen L. Barker <alb at datafilter.com> sanoi, hitaasti kuin hämähäkki:

I'm very curious why this work has never been published, except in this single
news article from over two years ago.  Any idea?

> Abstract
> This study focuses on the effect of low level microwave radiation on human
> EEG alpha and theta rhythms. During the experiment, 20 healthy volunteers
> were exposed to a 450 MHz microwaves with 7 Hz on-off modulation. The
> field power density at the scalp was 0.16 mW/cm2. Signals from the
> following EEG channels were used: FP1, FP2, P3, P4, T3, T4, O1, and O2.
> The experimental protocol consisted of one cycle of short term photic and
> ten cycles of the repetitive microwave stimulation. The changes caused by
> photic as well as microwave stimulation were more regular on the alpha
> rhythm. In the majority of cases, photic stimulation caused changes in the
> EEG energy level in the occipital and microwave stimulation in the frontal
> region. Our experimental results demonstrated that microwave stimulation
> effects became apparent, starting from the third stimulation cycle. Changes
> varied strongly from subject to subject. Therefore, photic and microwave
> exposure did not cause statistically significant changes in the EEG
> activity level for the whole group. For some subjects, clear tendencies of
> changes in microwave on-off cycles were noticeable. Bioelectromagnetics
