The experiments were performed on four groups of subjects with different pulse rates. After recording the reference EEG for 10 minutes, exposure at the first pulse rate was applied, followed by one or two further pulse rates according to the considered group. During each test session, RF and sham exposure as well as the succession of pulse rates were randomly assigned.
Statistically significant changes occured in the EEG rhythm energy and dynamics between 12% and 30% of subjects. Theta wave was least affected. Most changes were observed in beta waves. Concerning brain region major changes were revealed in temporal-parietal brain region. Statistically significant changes in the EEG rhythms took place at the pulse frequencies higher or close to the EEG rhythm frequency.
