Abstract
Recent development in the theory of point processes were used to analyze the accuracy by which signals are conveyed by the discharges of single auditory-nerve fibers. The only spike trains which can convey a signal without distortion were those well-described by a Poisson process model. Theoretical predictions were made of the distortion present in the transmission of signals by auditory-nerve fiber discharge patterns. Absolute refractory effects were shown to result in more distortion than relative refractory ones. Procedures were developed to compensate for these distortions. The procedures designed to compensate for absolute refractory effects opreate on the PST [post stimulus time] histogram. Computer simulations are used to confirm the theoretical predictions and to assess the accuracy of the compensation techniques.
