A method of brain wave analysis is to be implemented using a brain wave measuring instrument and a medical device. The method includes transmitting a nerve stimulation signal to cerebrum of a patient, measuring the nerve stimulation signal through the body of the patient so as to obtain discharge time information, measuring a brain wave signal from a head portion of the patient, obtaining energy distribution information according to the brain wave signal, and calculating behavior information according to the discharge time information and the energy distribution information.一種腦波分析方法，適用於一腦波儀及一醫療元件，該醫療元件植入患者的身體並藉由神經與大腦連接，該腦波分析方法包含下列步驟：(A)該腦波儀由患者身體量測得來自於患者大腦並與該醫療元件相關的一神經刺激訊號，並獲得一放電時間資訊；(B)該腦波儀由患者頭部量測一腦波訊號；(C)該腦波儀根據該腦波訊號獲得一能量分布圖；及(D)該腦波儀根據該放電時間資訊及該能量分布圖，計算一表現數據。
