I got to know that the electrodes have to be placed in the motor cortex area so as to detect the movements from various body parts like face,foot,tongue,arms etc.My EEG machine has only 19 electrodes so i placed all the electrodes in motor cortex region rather than placing them as in 10-20 system but i got all the EEG signal changes at the same set of electrodes. Can anyone help me out how to distinguish the signals and why the signals were not coming on electrodes corresponding to that concerned organ.Pleaseguide how to locate the electrode positions for detecting these movements
