Figure 2. Sound-evoked whole-nerve compound action potential (CAP) thresholds were determined prior to acoustic overstimulation (Le Prell et al., 2001b, Le Prell et al., 2003) and after exposure to a 110-dB SPL 10-kHz tone for 20-min (Le Prell et al., 2001b). Threshold shift (i.e., change from baseline) is depicted immediately post-exposure (top) and 90-min post-exposure (bottom). There were no statistically reliable differences between intact control animals and LSO-lesioned animals at either timepoint.
