Animal research open field test

for preclinical researchfor rodentsfor mice

Introduction
The open field test evaluates locomotor activity and anxiety-related behavior in rodents. Rodents typically avoid brightly lit, exposed areas and prefer peripheral zones; changes in exploration patterns reflect anxiety levels and motor function.

Yuyan Instruments supplies an open field system composed of an Open Field Cage, video acquisition hardware and behavioral video analysis software. The system records sessions and automatically extracts behavioral parameters to support objective assessment of locomotion and anxiety. Available models: mouse, rat and a universal model compatible with both species.

Features

• Species-adapted design: Cage dimensions and materials correspond to morphological and experimental requirements for mice and rats to ensure comparable conditions across trials.
• Low experimental interference: Video acquisition minimizes manual handling and observer bias, reducing stress-related artifacts in behavior measurements.
• Automated tracking and analysis: Software automatically detects subjects, reconstructs trajectories and computes quantitative parameters (distance, speed, center vs edge time).
• Data export and integration: Outputs trajectories and behavioral metrics in standard formats for downstream analysis and record-keeping.

Application Field
The open field test is used in preclinical research to assess locomotor activity, exploratory behavior and anxiety. Typical applications include neuropsychiatric and neurodegenerative disease models (anxiety, depression, Alzheimer’s, Parkinson’s), pharmacology and toxicology studies, and behavioral phenotyping of transgenic models.
