Poor temporal processing is reflected in the decreased rate-following ability in Cntnap2^−/− rats. (A) RRTF reveals that the subsequent capacity of Cntnap2^−/− multiunit clusters is poorer than wildtypes at repetition rates of 7.4 and 9.2 pps despite knockout clusters having an increased firing rate as compared with the first noise burst in the six-pulse train. The average firing rate to noise bursts 2–6 in the six pulse train are represented by the solid line, with error bars denoting SE. Dashed line and shaded region represent the mean firing rate ± SE to the first noise burst. (B) The tMTF normalizes the RRTF to the firing rate in response to the first noise burst stimulus showing that in both wildtype and Cntnap2^−/− rats, the ability of multiunit clusters to follow repeated stimuli begins to decrease at a repetition rate of 2.8 pps. (C) The f_h1/2 confirms that Cntnap2^−/− multiunit clusters have a poorer capacity for processing high-rate stimuli as the rate at which the tMTF of each cluster was at half its maximum is lower in Cntnap2^−/− rats compared with wildtypes.
