Rodent Physiologic Analysis and Recording (RODAR) System Evaluation Concludes

The overall goal of this multi-year R&D program was to design, build, and evaluate the RODAR system. The RODAR system provides the capability to monitor multiple vertebrates simultaneously, with continuous recording, synchronization, and display of physiological and/or environmental data. Physiologic data are collected via miniature, lightweight Remote Physiologic Modules (RPMs) that are worn on the dorsal surface of the animal, with sensors integrated into an adjustable jacket. Environmental data are collected using wireless Remote Environment Modules (REMs) that can be placed in living quarters or experimental environments. Remote Bridge Modules (RBMs) will be available that accept arbitrary analog inputs (e.g., from third-party/custom sensors) and seamlessly integrate such data with native RODAR sensors.

Studies using both awake and anesthetized rats and mice demonstrated accurate measurement of respiratory rate, heart rate, activity, and temperature. The jackets were well-tolerated by the animals, even for periods of 24 hours or longer.
