This invention is a mobile wearable electromagnetic brain activity monitor comprising a frame worn on a person's head, electromagnetic energy sensors which collect data concerning the person's electromagnetic brain activity, and a control unit. The electromagnetic energy sensors can be electroencephalogram (EEG) electrodes. In an example, the frame can be circular. In an example, the frame can loop around the person's head from one ear to the other ear. In an example, the frame can be an eyewear frame which also includes light-transmitting optical members.
