Determining Ultrasonic Vocalization Preferences in Mice using a Two-choice Playback Test

Defects in Ultrasonic Vocalization of Cadherin-6 Knockout Mice

BACKGROUND Although some molecules have been identified as responsible for human language disorders, there is still little information about what molecular mechanisms establish the faculty of human language. Since mice, like songbirds, produce complex ultrasonic vocalizations for intraspecific communication in several social contexts, they can be good mammalian models for studying the molecular...

Developmental Ssri Exposure Alters Ultrasonic Vocalization in Mice

Altered ultrasonic vocalization in mice with a disruption in the Foxp2 gene.

Neurobiology of speech and language has previously been studied in the KE family, in which half of the members have severe impairment in both speech and language. The gene responsible for the phenotype was mapped to chromosome 7q31 and identified as the FOXP2 gene, coding for a transcription factor containing a polyglutamine tract and a forkhead DNA-binding domain. Because of linkage studies im...

Song type matching as threat: a test using interactive playback

Neighbouring song sparrows, Melospiza melodia, in our Seattle population share song types and sometimes respond to neighbour song by type matching (replying with the same song type being sung) or repertoire matching (replying with a shared song other than the type being sung). Based on our modification of the threat hypothesis of Krebs et al. (1981, Animal Behaviour, 29, 918–923), according to ...
