Advances in the measurement technique, technology, analysis methodology and means of validating the data have increased the reliability, but the ambivalence of single-patient measurements is still high. The measurement error cannot be standardized without control over the total quality. Increased number of trials would improve the signal-to-noise-ratio of the grand average, but the disadvantage is the fatigue of the patients. The major issue is to decide the optimal number of trials.This study presents a novel recording procedure for ERP studies where the amount of recorded trials is automatically adjusted online according to the initial quality of the data and the desired quality of the measurement outcome. The process was simulated offline using prerecorded ERP data from a MMN study. The preliminary results suggest that the repeatability of the average waveform and, thus, the reliability of the measurement were improved. However, further testing is required before the online implementation.
