This question is pretty straight forward:
What is the real difference (if any) between EEG, EMG, EOG and EKG? All of them registers electrical activity, measured by placing electrodes on the skin, right?
I understand that they indirectly measure different things (that is, neuronal activity, muscle activity et cetera) with the use of different setups (electrode type, size et cetera), but is there really any difference between them, in what and how they really measure what they are trying to measure?
