This mouse is one of many restrained in a device developed in a University of British Columbia laboratory in which an air-powered metal piston rapidly strikes the animal’s skull, causing the head to whip backward and rotate. Now, the experimenter is using this method in a purported attempt to model traumatic brain injury associated with so-called “intimate partner violence,” including procedures that compress animals' neck blood vessels and airways in a crude attempt to replicate “nonfatal strangulation.”
