Cntnap2  ^−/− cortical auditory evoked potentials in adulthood reflect an immature-like profile. (A) Averaged CAEP waveforms from wildtype (n = 180 waveforms) and Cntnap2^−/− (n = 161 waveforms) rats in response to a 90 dB SPL noise burst. Solid line and shaded region denote mean ± SE. (B) Increased amplitudes and (C) prolonged latencies of the N1 and P2 potentials reflect an immature-like response profile in the adult rats. Data represented as mean ± SE. ^*P < 0.05.
