''Alpha waves'' are one type of [[Neural oscillations|brain waves]] detected either by [[electroencephalography]] (EEG) or [[magnetoencephalography]] (MEG) and predominantly originate from the [[occipital lobe]] during wakeful relaxation with closed eyes. Alpha waves are reduced with open eyes, drowsiness and sleep. Historically, they were thought to represent the activity of the visual cortex in an idle state.  More recent papers have argued that they inhibit areas of the cortex not (contracted; show full)[[fa:امواج آلفا]]
