Article Title: The temporal organization of mouse ultrasonic vocalizations
doi: 10.1371/journal.pone.0199929
Figure Lengend Snippet: (a) Example spectrogram showing short and long USVs in adult male ultrasonic courtship vocalizations. (b) Example histogram of USV duration for one mouse with the fit of two Gaussians overlaid. Also labelled are the Gaussian centers and Gaussian weights, the intercept of the two Gaussian distributions representing the cutoff between short and long USVs in the animal, and the Ashman’s D score for the distribution. (c) The sum of the fit of two Gaussians to the USV duration distributions from all 19 adult mice. (d) The average Gaussian centers from the duration distributions of short and long USVs in all 19 mice, as well as the cutoff values between the two distributions. (e) The average proportions of short and long USVs produced by all 19 mice. (f) The Ashman’s D scores for each of the 19 animals’ USV duration distributions; a score of 2 or greater represents significant separation between two distributions. In (d-f), error bars indicate the mean across mice +/-1 standard deviation, and values for individual mice are represented by the 19 overlaid points. Summary statistics for (d-f) are presented in .
Article Snippet: All Gaussian fits were performed using Matlab’s ‘gmdistribution.fit’ function with a maximum of 500 iterations.
