Abstract : Electrophysiological investigations of the auditory cortex frequently reveal single neural units which respond in a transient manner mainly to stimulus onset. Characteristics of these transient response patterns were investigated with paired tone or noise bursts. Neural threshold shifts following the initial response were estimated by determining the relative magnitude of the response evoked by the initializing and probe stimulus bursts. The results of these experiments support the hypothesis that changes in the neuron's sensitivity following the initial response account for the transient response pattern. (Author)
