EEG; FFT; audio-visual stimulation; EMF stimulation.


The effects of different induced extremely low frequency (ELF) electromagnetic field, audio (binaural-beat), visual (light flashes) and combination of audio and visual rhythms at the various electroencephalographic (EEG) rhythms were investigated. These experimental findings suggest that EEG activity under exposure to EMF 0.174mT (8.33Hz) sinusoidal low intensity EMF exhibited a substantial decrease in delta and theta bands and prove that there is a slight transition from beta to alpha band from beta-alpha ratio calculations of the Energy Spectral Density. During the visual and audio visual stimulation at alpha rhythms (i.e. 13-7.5Hz) a possible entrainment on overall EEG activity was elicited by substantial increase and decrease in spectral energy levels.
