Regel S, Gottselig, J, Schuderr, J, Tinguely, G, et al. (2007):

The authors recruited 24 right-handed, healthy young males for this study. They participated in three experimental conditions at weekly intervals, in a double-blind, randomized, crossover design: exposure to a pulse-modulated (PM) RFR, a continuous wave (CW) RFR, or a sham exposure. Each exposure was for 30 minutes at 900 MHz, over the left hemisphere. The peak spatial SAR was 1 W/Kg. The subjects performed 3 tests of cognitive function during exposure, and an EEG was recorded for 6 minutes at 0, 30, and 60 minutes after exposure.

There were no changes in simple reaction time or in 2-choice reaction time. In the 2-back and 3-back tasks, reaction time was decreased in the PM exposure. Accuracy was increased in the 3-back test in the PM exposure. The EEG was also affected in the PM exposure, but only at 30 minutes. There was enhanced spectral power in the 10.5-11 Hz range. There were no effects from the CW exposure.

Other authors have reported decreased reaction times and changes in the alpha range on the EEG with RFR exposure, especially with PM exposure, but the results have not been consistent.
