主要规格&技术指标
1. Pre-Test Preparation
Ensure that all equipment, including the camera, acquisition system, and software, is functioning correctly before the session. Turn on the lights and maintain consistent ambient lighting throughout the experiment to reduce variability. Animals should be transported to the testing room in their home cages and allowed to acclimate for at least 30 minutes before testing.
2. Arena Cleaning
Before each session, thoroughly clean all open field arenas using 75% ethanol to eliminate any residual odors or biological traces from previous animals. Wipe down the walls and floor of each chamber with ethanol-soaked wipes, and allow the surfaces to air dry completely.
3. Camera and Mounting Setup
Connect the camera to the tracking system using a video capture card. Adjust the camera angle and position to make sure all arenas are clearly visible in the software’s video feed without distortion or occlusion. Confirm that the camera is level and properly focused.
4. EthoVision XT Software Setup
Open the EthoVision XT software and create a new experiment configuration. Define each of the four open field arenas as separate zones, each measuring 40 cm × 40 cm. Within each arena, define a center zone of 20 cm × 20 cm, centered geometrically. Use the live camera feed to verify that the defined zones match the physical layout accurately. Set the session duration (e.g., 5–10 minutes) and confirm detection settings.
5. Behavioral Testing Procedure
Place each animal gently into the center of its respective arena, minimizing handling and avoiding external disturbance. Avoid any sudden noise or vibrations during the test.
6. Post-Session Cleaning and Data Management
After the session ends, stop the recording. Remove the animals and return them to their home cages. Immediately clean the arenas again using 75% ethanol, removing any feces, urine, or scent marks.
主要功能及特色
The open field test is a widely used behavioral paradigm to assess general locomotor activity, exploratory behavior, and anxiety-related responses in rodents. The 4-chamber open field system is designed for high-throughput behavioral analysis of rodents, allowing simultaneous tracking of up to four animals in independent arenas. Each chamber typically measures 40 × 40 × 40 cm and is constructed from non-reflective, high-contrast materials optimized for video tracking. A high-resolution overhead camera captures real-time footage at ≥25 frames per second, ensuring smooth and accurate tracking. The system includes uniform illumination—either visible or infrared—suitable for both diurnal and nocturnal testing. EthoVision XT serves as the core tracking software, enabling automatic detection of animal position, movement trajectories, velocity, and mobility states. Users can define custom zones (e.g., center vs. periphery) to quantify key behavioral metrics such as time spent, entries, and latency.
