Average potentials synchronized with cardiac cycle, motor activity, auditory stimulation, and visual stimulation were reliably detected and isolated in the electroencephalographic activity from one pair of scalp leads. The results indicate that the averaging technique need not be limited to the detection of potentials directly evoked by sensory stimulation. The data also demonstrate that if is possible to detect and measure several average potentials in a single human electroencephalographic recording. In addition, the data show that time-locked average potentials simultaneously present in a given electroencephalographic recording can summate in an algebraic manner. This suggests that a major portion of conventional electroencephalographic recordings may consist of the algebraic sum of a number of concomitant specific potential changes. The averaging technique is suggested as a general method whereby component parts of electroencephalographic activity can be separated for systematic experimental analysis. Author
