This report presents a student-led EEG pilot study on how alpha and beta wave patterns change between calm and excited states. Using a FreeBCI 8-channel EEG system, recordings were collected from adolescent participants during eyes-closed seated rest and eyes-open phone engagement. The main observation was that calm recordings tended to show stronger alpha-related patterns, while excited recordings showed denser and faster activity linked to beta waves. A small follow-up check using a consumer EEG headband supported the same general trend, although those data were used only as visual evidence. This project is exploratory and is not intended for diagnosis.
