A Conditioned Behavioral Paradigm for Assessing Onset and Lasting Tinnitus in Rats
Thresholds were elevated across all frequencies in tinnitus(+) and tinnitus(-) rats at post-exposure day 0, revealing immediate and significant hearing loss. By post-exposure week 7, however, thresholds recovered to pre-exposure levels. At all time points, thresholds were similar between tinnitus(+) and tinnitus(-) rats. There were no threshold elevations in control rats. Error bars represent standard error of the mean.
