The IC response strength to the consonant portion of the speech sounds is altered in VPA-exposed rats compared to saline-exposed rats. A Left, box and whisker plots showing the number of driven spikes evoked at each IC recording site for the consonant portion of each stop consonant sound. The driven rate was quantified using the 40 ms response to the consonant portion of the sounds. The black line indicates the median, and the error bars indicate the 95% confidence interval. The asterisk indicates experimental groups that are statistically significant from each other using a Mann–Whitney U test. Right, box and whisker plots depicting the average group response strength evoked by the consonants ‘d’, ‘g’, and ‘t’ presented at 60 dB. B Left, box and whisker plots showing the number of driven spikes evoked at each IC recording site for the consonant portion of each affricate sound. Right, box and whisker plots depicting the average group response strength evoked by the consonants ‘ch’, and ‘j’ presented at 60 dB. C Left, box and whisker plots showing the number of driven spikes evoked at each IC recording site for the consonant portion of each fricative sound. The driven rate was quantified using the 40 ms response to the consonant portion of the sounds. Right, box and whisker plots depicting the average group response strength evoked by the consonants ‘f’, ‘h’, ‘s’, and ‘sh’ presented at 60 dB
