These waveforms are produced by an electrical alteration of the recorded brain wave. It is important to realize that because the EEG is very sensitive to the recording of microvoltages, it is common to see the electrical effect of factors that occur outside of the skull. Although these disturbances do not represent brain abnormalities, their recognition is important because they can distort the recording of brain waves. [9]
