摘要：

Random or near random action potentials were recorded via a delay line. The potential triggered the sweep of the oscilloscope and was displayed after it had been delayed. A delay of 10 msec was necessary to display motor unit potentials in their full duration. Recording via a delay line reduced the recording time and the amount of photographic paper required and improved the accuracy in the evaluation of the potentials. Automatic switching between the leads of a multi-electrode combined with recording via two delay lines made it possible to determine the territory of a motor unit from the distribution of its potentials within a shorter time and with greater accuracy than in previously used procedures. © 1969.
