From: Degraded inferior colliculus responses to complex sounds in prenatally exposed VPA rats
The IC response strength to the vowel portion of the speech sounds is altered in VPA-exposed rats compared to saline-exposed rats. A Box and whisker plots showing the number of driven spikes evoked at each IC recording site for the vowel portion of each speech sound. The driven rate was quantified using the 300 ms response to the vowel portion of the sounds. The black line indicates the median, and 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. B Box and whisker plots depicting the average group response strength evoked by the vowels ‘a’, ‘ee’, and ‘oo’ presented at 60 dB
