Research from the University at Buffalo suggests that rodents produce ultrasonic vocalizations (USVs) to influence particle movement, enhancing their olfactory reception. This finding challenges ...

You can hear the ultrasonic vocalizations made by a rat when it is being tickled by a researcher. The vocalizations have been transposed to the human audible range.

Ultrasonic calls by rats may represent affective expressions and serve communicative functions. The temporal patterning and frequency modulation of the long, 21-30 kHz ultrasonic calls were studied in ...

Ultrasonic vocalizations (USVs) in rats are thought to contain ecological signals reflecting emotional states. These USVs are centered on 50-kHz, and frequency modulation (FM) is hypothesized to ...
