Voltage in time restricted passband control subject grand averaged ERPs to standard stimuli illustrating different neurophysiological signals and their overlap. The shaded box indicates 50–100 ms post stimulus. The top trace shows the averaged EAGBR response. The middle trace highlights the P1/P50 response, which appears to overlap to a great degree with the EAGBR. The bottom trace shows N1/N100 and P2/P200. Note that the N1 response begins at approximately 75 ms and overlaps partially with the EAGBR and P1.
