Introduction to Animal Models of Anxiety Disorders

Animal models of anxiety can mimic human anxiety‑related disorders, with diverse modeling approaches and robust stability. These model animals typically exhibit hallmark anxiety‑like behaviors, including abnormal spontaneous activity, heightened vigilance, pronounced avoidance tendencies, and reduced exploratory behavior, making them a widely used experimental tool for investigating the pathophysiological mechanisms of anxiety and for screening and evaluating relevant pharmacological agents.

Modeling cycle	1–2 weeks
Laboratory animals	Mice and rats of SPF grade
Positive drug	Primarily exerting anxiolytic, sedative, and neuro‑modulatory effects, it can effectively alleviate anxiety‑related symptoms in animals.
Application areas	This model is widely employed in elucidating the pathogenic mechanisms of anxiety disorders, screening candidate drugs, and evaluating drug efficacy and safety. It also supports the development of novel psychotropic medications, the identification of therapeutic targets, and the preclinical validation of various intervention strategies.

Construction of an Animal Model of Anxiety Disorder

Currently, a variety of anxiety models are in use, which can be broadly categorized into two types: one is the unconditioned‑reflex anxiety model, encompassing exploratory‑behavior and social‑behavior paradigms; the other is the conditioned‑reflex anxiety model. Each of these categories has its own strengths, as well as corresponding limitations.

Common methods for constructing unconditioned-reflex–based anxiety models include the elevated plus-maze test, the open-field test, the light–dark transition test, the ladder-climbing test, and the four‑plate test.

Common methods for constructing conditioned anxiety models include the conflict paradigm and the safety signal removal paradigm.

Model features:

Using the animal’s exploratory behavior in novel environments and its fear of elevated, open spaces to elicit conflicting responses is a classic assay in the study of anxiety-related behaviors.
