The temporal organization of mouse ultrasonic vocalizations - Fig 7

(a) Example spectrograms of USVs produced by a single mouse throughout development. (b) Mean pup USV, short USV, and long USV duration across mice over time. (c) Mean IVI duration across mice throughout development. (d) Mean weighted frequency of pup USVs, short USVs, and long USVs over time. (e) Mean pup USV duration at P12-P16 was significantly correlated with mean (e.i) short USV and (e.ii) long USV duration at P17-P34; (e.iii) median IVI duration at P12-P16 was also significantly correlated with median IVI at P17-P34. In (b-d), significance is assessed with repeated-measures one-way ANOVAs with Tukey’s correction for multiple comparisons; see S27 and S28 Tables for statistical details. Summary statistics are presented in S25 and S26 Tables. Error bars indicate the mean value across animals +/- 1 standard deviation. Individual lines indicate the values for each mouse. In (e), Spearman’s R and p-values for the correlation are labelled on the respective plots.
