Intact auditory brainstem responses in adult Cntnap2^−/− rats. (A) Averaged BAEP waveforms from wildtype (n = 7) and Cntnap2^−/− rats (n = 8), in response to a 90 dB SPL, 0.1 ms click stimulus. Solid line and shaded region denote mean ± standard error (SE). (B) Amplitude and (C) latencies of peaks I and IV representing activity from the auditory nerve and lateral lemniscus terminating at the inferior colliculus respectively, represented as mean ± SE.
