Short-term adaptation and incremental responses of single auditory-nerve fibers

摘要: In response to tone bursts of constant sound intensity, mammalian auditory-nerve fibers produce a maximum firing rate at onset, followed by an adaptation quasi-steady within about 150 msec. On the basis two fundamental findings, it appears that is additive, or linear, in nature and does not result from multiplicative gain change. Basically, given increment stimulus intensity produces same change before after adaptation. addition, relative amount adaptation, i.e. ratio driven onset steady-state rate, independent intensity. Nonlinear effects appear experimental results may be accounted for static nonlinearities, one preceding following linear stage.
