NCT02906228

Brief Summary

The purpose of this study is to investigate possible effects of radio frequency electromagnetic fields on EEG activity during sleep and on Brain function during wake (EEG in the resting state condition, slow EEG potentials, auditory evoked potentials) and cognitive performance measures in test of selective attention, divided attention and working memory in healthy elderly females (60 - 80 years).
