To perform VER studies, use the TSD122 Stroboscope and the averaging mode of the MP System. The stroboscope will trigger the MP System or the averaging software can trigger an external stimulator. An Evoked Response or Electroencephalogram Amplifier (ERS100C or EEG100C) is used to record the evoked response while the software performs on-line averaging. The averaging software allows the user to set the number of averages and the length of the average, and to adjust the artifact rejection criteria. Display and overlap multiple responses for a quick comparison between subjects and trials.
