Normalized startle amplitudes and mean spontaneous rates in sham and noise-exposed animals with and without tinnitus. A: normalized startle response amplitudes were evaluated for each noise exposure frequency band for sham (black bars), ENT (dark gray bars), and exposed-tinnitus (ET; light gray bars) animals. Error bars indicate 95% confidence interval. Stars indicate statistical significantly different means in the same frequency band. B and C: mean spontaneous rate (spikes/s) evaluated for S, ENT, and ET animals for units with BF below (B) and above (C) 12 kHz. No ENT neurons have been found at CF >12 kHz. The error bars indicate SE (adapted from Koehler and Shore 2013a). BBN, broadband noise.
