FIG. 7.

Data from tinnitus⁽⁺⁾ animals showing that ACES did not decrease the amplitudes of startle-only responses (background sounds without silent gaps) at lower frequency bands (6–8 and 10–12 kHz) and BBN. Instead, ACES tended to restore/enhance tone exposure-attenuated amplitudes of startle-only responses, especially for high-frequency bands at which gap detection was compromised and behavioral evidence of tinnitus was robust (compare gray and black bars). The restoration of the amplitudes of startle-only responses was significant at 26–28 kHz and marginal at 14–16 kHz.
