Abstract

In recent years there has been increased interest within the laboratory animal science community in automated profiling of rodent activity in their home cages. Activity data may reflect health, welfare, phenotype and/or effects of toxicity. Video-based systems offer distinct advantages in being able to recognize discreet behaviors, and some video-monitoring functions have been designed into specialized mouse racks. Wide-spread use of this technology may be achieved by retrofitting existing high capacity racks with video-monitoring capability and developing data management tools. We demonstrate a mechanical design that utilizes 3-D printing technology and inexpensive electronic components. The design employs a high-resolution depth and RGB image camera. The system is built to integrate into Allentown NexGen racks. Algorithms are being developed to provide detailed analysis of rodent activity within their home cages on ventilated racks.
