Figure 4

Typical indicative sonograms of ultrasonic vocalizations of mouse pups illustrating nine distinct call categories. From left to right and from top to bottom: ultrasonic vocalization representing short, chevron, complex, flat, upward, downward, two-components, frequency steps and composite call categories. Time (in milliseconds) is indicated by the X-axis, frequency (in kHz) is indicated by the Y-axis. *Intensity data (as shown in color) is indicative of relative values and does not represent real intensity outcomes.
