This Round Chamber is a cornerstone in behavioral neuroscience research, offers a versatile arena for exclusive use in rodent studies: Open Field Test, Rotational Behaviors, Novel Object Recognition, Fear Conditioning, and Social Interaction Studies. For research purposes ONLY.
- Chamber Structure: The chamber is round, typically constructed from transparent materials like acrylic or plexiglass. It may vary in diameter depending on the research requirements but often measures around 60 to 90 centimeters (approximately 24 to 36 inches).
- Flooring: The chamber floor is usually made from non-slip materials to ensure stable footing for rodents during assessments. The flooring may be removable for easy cleaning between trials.
- Lighting: Adjustable lighting systems, including overhead lighting and wall-mounted lighting, provide controlled illumination to suit different experimental paradigms.
- Video Cameras: High-resolution video cameras are strategically positioned to record rodent behavior from various angles. These cameras capture invaluable data for subsequent analysis.
Preparing the Round Chamber
Before commencing experiments, ensure the Round Chamber is clean, free from any residual odors, and devoid of physical irregularities that might influence rodent behavior. Place the chamber in a controlled environment with consistent lighting, temperature, and minimal external disturbances to ensure data reliability.
Animal Selection and Habituation
Carefully select rodents that align with your research objectives, considering factors such as age, gender, and genetic background. Allow them to acclimate to the testing room. Gradual habituation to the chamber environment is vital.
Conducting Behavioral Assessments
Initiate the experiment by placing the rodent into the Round Chamber and allow it to explore the environment freely. Researchers often employ various behavioral paradigms, including but not limited to:
Open Field Test (OFT):
This paradigm assesses spontaneous locomotor activity, exploration, and anxiety levels in rodents as they navigate the chamber.
Rotational Behaviors in Freely-Moving Animals:
Rotational behaviors in freely-moving animals, such as circling in a clockwise or counterclockwise direction, serve as valuable indicators of dopaminergic system activation and efficacy in behavioral neuroscience research. The behaviors can be assessed using Smart v3.0 PanLab.
Novel Object Recognition (NORT):
Researchers introduce novel objects into the chamber to assess the rodent’s ability to recognize and preferentially interact with unfamiliar items.
The chamber can be adapted for fear conditioning experiments, enabling researchers to study fear response and memory formation in rodents.
Social Interaction Studies:
Researchers can use the chamber to investigate social behaviors, sociability, and preference for social interactions.
Data Analysis and Interpretation
Post-experiment, analyze the collected behavioral data to evaluate the rodent’s performance based on the specific assessment paradigm employed. Interpret the results within the context of your research objectives to gain insights into various aspects of rodent behavior.
