Alpha waves are one type of brain waves detected either by electroencephalography (EEG) or magnetoencephalography (MEG) and predominantly originate from the occipital lobe during wakeful relaxation with closed eyes.
The electric currents administered were designed to enhance alpha wave oscillations, naturally occurring electrical patterns that oscillate at a frequency of 8 to 12 hertz (cycles per second). When you're daydreaming or in another restful waking state, there's a good chance that your brain is in alpha mode.
