Identifying voluntary components of human movement-related cortical potential using dynamic spectrum

Summary form only given. The electroencephalogram (EEG) has been generally known as a non-destructive method to examine the function of the human brain. This paper presents the identification of the time frequency components of the Movement-Related Cortical Potential (MRCP) associated with human voluntary muscle behaviors using the 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. Voluntary activity was recorded with the electrode placed on the palm side of the metacarpophalangeal joint when the subjects flexed their right-hand index finger and their eyes were closed. I have found insights into the temporal dynamics of the MRCP. This method doesn´t need many trials to identify the time frequency components of the MRCP.
