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.
Alpha wave biofeedback has been shown to be a useful tool for treating anxiety and depression. Because alpha waves are linked with relaxed mental states, an increase in alpha wave activity is the goal of most biofeedback training. EEG can be used to provide moment-to-moment feedback when alpha waves increase or decrease. Mindfulness training and meditation tend to produce noticeably more alpha waves without the use of technological machinery.
