The advent of the pre-pulse inhibition model has shown that it can be a fast and effective means of measuring the pitch of tinnitus in rats. In this study, the pre-pulse inhibition model was used to determine the pitch of salicylate induced tinnitus in the presence of two levels of background stimuli, 48 and 60 dB SPL. Results showed that a significant difference of PPI was present when comparing baseline and salicylate responses at 16 kHz for the 48 dB SPL background level, indicating the presence of tinnitus with this frequency. Unlike past studies, a significant finding for the 60 dB SPL background level was not found.application/pdfxii, 130 pagesengCopyright protected, all rights reserved.TinnitusRats as laboratory animalsSalicylatesText
