Note: $\overline{x}$ = mean; SD = standard deviation; WPS = weeks post-surgery; IVI = intervocalization interval; s = seconds; ms = milliseconds; bold values with an asterisk (*) = statistical significance (p < 0.05) between Sham and Transection groups at 1 WPS. Two mice from the transection group were excluded due to lack of calls.
