Manual delivery of electric stimulus (in some experiment modes)

Tracking of speed when the animal falls off the running surface.

Assessment of animal performance in watts (activated when a value larger than 0 is entered in the Angle of Gradient field)

Recording of the phase number in which the light barrier interruption occurred

Calculation of time from the start of the phase up to the light barrier interruption

Metabolic Treadmill for Mice and Rats

A Metabolic Treadmill for small laboratory animals is a fully computerized, electronically controlled system for exercise calorimetry or investigating the effectiveness of drugs or impaired motor coordination of the skeletal muscles. Available for mice and rats, it has one compartment, air-tight cover, and perforated lid for training purposes. The system comes as a stand-alone unit, which is connected to a respirometry system – a module of PhenoMaster.

On-demand, the floor grid can be equipped to apply an electric stimulus. 

The system runs according to a user-defined exercise protocol created with the help of user-friendly software. It allows a seamless integration of Stellar telemetry for various physiological data recordings at freely moving animals.
