The Open Field Test is a rodent behavioral assay that measures spontaneous locomotion, exploratory behavior, and anxiety-like behavior when an animal is placed in a novel open arena. The main readouts are total distance traveled, movement time, velocity, center-zone entries, center-zone time, peripheral-zone time, and thigmotaxis. The assay is based on the conflict between exploration of a novel environment and avoidance of exposed open areas; higher center exploration is commonly interpreted as lower anxiety-like behavior, whereas increased wall-following or peripheral occupancy is interpreted as higher anxiety-like behavior.
Open Field Test (OF)
The open field test (OF, Open Field Test) is an experiment used to evaluate the activity level, exploratory behavior and anxiety state of mice or rats. In experiments, animals are placed in an open, usually square area, and their movements and behavior in the new environment are recorded. Typically, an animal's activity in a new environment, exploratory behavior, and anxious response to its surroundings are observed and analyzed. Open field experiments are widely used to study behavioral, neuropharmacological and anxiety symptom models, providing a simple and effective method for drug screening and neurobiological research.
