The Operant Conditioning Wall for Automated Cognition Testing in the Home Cage.

Operant wall

Modular Innovation, Streamlined Experiments, and Stress-Free Learning

The Operant Wall, featured in PhenoMaster, is a unique integrated into metabolic home cage, operant testing platform available. Conduct fully automated operant conditioning experiments without user interference, ensuring no stress for the animal, thus preserving learning performance and data integrity. The homecage setup is ideal for extensive, long-term experiments, enabling more trials per animal and facilitating circadian analysis of learning abilities. Additionally, it streamlines the experimenter’s workload and conserves valuable laboratory space. Operant Walls for rats and mice are customizable from hardware modules tailored to individual tasks. The system offers unparalleled versatility, whether studying motivation, attention, impulsivity, or conducting simple learning tasks.

Tailor-Made Operant Walls

Construct a highly adaptable operant wall system precisely aligned with your research requirements. Our extensive selection of modular components empowers you to configure the ideal setup for your specific behavioral experiments.

  • Reward Versatility: Seamlessly integrate food or liquid reward dispensers, facilitating efficient protocol switching between sessions.
  • Precise Delivery Systems: Utilize ultra-precise liquid dispensers, suitable for both oral and intravenous drug self-administration studies.
  • Suitable for Diverse Tasks: Select a range of operant modules like nose-pokes, levers, and LED lamps. These modules provide precise control over stimuli presentation and response recording, allowing you to design complex learning tasks.
  • Enhanced Motivational Cues: Integrate PhenoMaster food and liquid containers in conjunction with access control units. Restricting access prior to experiment initiation demonstrably increases subject motivation for reward acquisition.


Empowering diverse behavioral research, this operant wall fosters customized testing environments.

We Bring Experiment to the Animal

Animals adapt to the Operant Wall much quicker than to Standard Skinner boxes. This reduces the duration of the experiment

Independent operation in all Operant Wall units – animals can proceed through complex multi-step paradigms at their speed

High level of flexibility regarding generation of experimental tasks – easy-to-use graphical user interface – no programming knowledge required

Long-term experiments allow accurate circadian performance analyses

High-throughput multi-cage setups – reduced workload for the experimenter

Combine respirometry for cognitive testing in metabolic research – unique on the market!
