Dr. Charles Schaefer, a postdoctoral fellow working with Dr. Tobias Riede at Midwestern University presented research at the conference examining how rats use deep breaths to produce ultrasonic vocalizations.

Similarly, researchers have studied a variety of vocalizations in rats that signify positive as well as negative emotions and how their brains process this information. Did you know rats enjoy being tickled?
