Barbering in Laboratory Rodents: Problems and Prospects

Barbering is a behaviorally induced alopecia (hair and whisker biting) often observed in laboratory mice and rats. The role of this behavior is actively discussed, in particular, its relationship with stress, aggression, grooming and aberrant stereotypic behavior. Understanding the nature of barbering and its content in the state of laboratory animals is an important factor to consider in experimental work. Here, we discuss recent data on the neurobiology and genetics of barbering, as well as its role in the behavior and central nervous system of rodents.
