Ultrasonic calls emitted by mouse pups are whistle-like sounds with frequencies between 30 and 90 kHz. These signals play an important communicative role in mother-offspring interactions, since they elicit in the dam a prompt caregiving response. Both physical and social factors modulate ultrasound emission. Recently, an approach based on sonographic analysis has allowed a deeper investigation of this behavior, providing a detailed characterization of the features of ultrasonic call structure. Overall, studies on mouse pup ultrasonic calls have shown that the rate of emission of these signals follows an ontogenetic profile, the different sonographic types are emitted according to the environmental context, and different mouse strains emit specific repertoires of sonographic types. © 2010 Elsevier B.V.
