Regularities in the Songs of Individual Mice

<div><p>All seven mice with four or more qualifying trials (see text) are analyzed.</p> <p>(A) Syllable usage for three of the more common syllable types for three different mice. Error bars represent the standard error of the mean across trials.</p> <p>(B) Patterns of syllable usage on individual trials across mice. Each point corresponds to a single trial, where the trials from a particular mouse are marked with a consistent color and marker. For mice 1–3, colors are consistent between (A) and (B). Placement of points in the plane reflects the pairwise “distance” between trials, where that distance measures the overall differences in percentage of each syllable type (see <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.0030386#s4" target="_blank">Materials and Methods</a>). Projection into two dimensions was performed by isomap.</p> <p>(C) Temporal regularities in song structure. Transition probabilities for all qualifying trials grouped by mouse.</p>
