Electroencephalogram (EEG) has been generally known as a non-destructive method to examine the function of human brain. This paper presents identifying time frequency components of human Movement-Related Cortical Potential (MRCP) accompanying with the human voluntary muscle behaviors using Wavelet Transform. The EEG was recorded with the 5-channel referential derivations, Fz, Cz, C3, C4, Pz, referenced to the right earlobe based on the international 10-20 system. The voluntary activity was recorded with the electrode arranged on the palm side of the metacarpophalangeal joint when the subjects flexed the right-hand index finger and eyes closed. About 10 Hz signals were recorded at all electrodes when the voluntary activity started. The higher level signals of about 10 Hz were recorded at Fz from about 0.4s after the activity started. About 5Hz signals appeared from about 1.0s to 0.2s at all electrodes before the activity started. This method isn't needed many trials to identify the components of the MRCP.
