Research

In order to improve our understanding of the neural and behavioral mechanisms of adaptive and maladaptive fear, investigators use a variety of translational animal models. These models are particularly important for research that would be too invasive for human studies. Rodents such as mice and rats are common animal models, but other species are used. Certain aspects of fear research still requires more research such as sex, gender, and age differences.
