Table 1.
Description of Rat Behaviors.
Fig 1.
Examples of categorized 50-kHz calls (as originally described by Wright and colleagues [3]) taken from our data.
Fig 2.
Total number of vocalizations by call category.
Categories correspond to those shown in Fig 1. Bars indicate the total raw counts of vocalizations across Analysis 1 and Analysis 2 combined.
Fig 3.
Z-scores showing the probability of occurrence of each of the vocalization-behavioral combinations are graphically presented.
(A) Data from Analysis 1. (B) Data from Analysis 2. (C) Grand average of the results from Analysis 1 and 2. Colors indicate the z-score and the same color scheme is used for all subplots. Note that vocalizations and behaviors with very low rates of occurrence have been omitted, as it was not possible to run statistical analysis for these low-frequency events.
Table 2.
Ten strongest associations between behaviors and vocalizations are shown for Analysis 1.
Values are z-scores.
Table 3.
Ten strongest associations between behaviors and vocalizations are shown for Analysis 2.
Values are z-scores.
Fig 4.
Proportion of each behavior associated with vocalizations.
(A) Bars show the proportion of times each behavior type was accompanied by any vocalization within 100 ms of the onset of that behavior. (B) Same as A but vocalizations are counted within 100 ms of the offset of the behavior. (C) The proportion of times each behavior was accompanied by vocalization, broken down by the specific type of vocalization.
Fig 5.
Dendrogram showing the relative similarity of different call types based on behavioral correlates.
The x-axis shows the distance between pairs of vocalizations based on the correlation between their behavioral z-scores (i.e., the rows of Fig 3). The dendrogram was generated using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) algorithm. As with Figs 3 and 4, data from the 4 least frequent vocalizations have been omitted.
