Two‐tone suppression in auditory nerve of the cat: Rate‐intensity and temporal analyses

摘要: Responses to two‐tone stimuli were recorded from auditory‐nerve fibers in anesthetized cats. One tone, the suppressor, was set at a frequency above characteristic and fixed intensity. A second tone an excitatory varied The suppressor when sufficient level, always reduced response by amount equivalent number of decibels, regardless tone’s Estimates suppression magnitude derived shifts rate‐intensity function obtained present relative functions for alone. When suppressor‐tone intensity increased, likewise increased. two tones increasingly separated frequency, either varying excitor or decreased monotonically. Suppression behaved same manner whether nonexcitatory. separation small enough both neuron’s responses synchronized low‐order combination could be elicited. These usually possessed different characteristics resulted estimates which spuriously low. is normalized with regard position traveling wave maxima within cochlear duct, given seen independent.
