Abstract
A psychophysical experiment performed by Guttman, van Bergeijk, and David in 1960 showed that binaural auditory resolution of repetitively presented, closely spaced clicks improves as repetition rate is increased. We propose a model in which the action of a single neuron can account for the phenomenon; it depends on a self‐inhibition function that serves to vary temporal resolution with stimulus rate. Single‐spike (click) stimuli elicit output bursts of variable duration; burst lengths are controlled by an output‐derived feedback whose level depends on stimulus repetition rate. An electronic model of a neuron, simulating a cochlear‐nucleus unit, accurately replicates the essential features of the psychophysical data. Two time constants, estimated by extrapolation, are postulated for single units in the human auditory system.
