Zusammenfassung:	1 Department of Communication Sciences and Disorders, Hugh Knowles Center, Northwestern University, Evanston, Illinois; and 2 7089 Jefferson Mill Road, Scottsville, Virginia Submitted 4 June 2008; accepted in final form 24 August 2008 Spontaneous activity and frequency threshold tuning curves were studied in thousands of auditory nerve fibers in chinchilla. The frequency distribution of spontaneous activity rates is strongly bimodal for auditory nerve fibers with characteristic frequency
