The Columbus Instruments Rota-Count system is designed to measure rotational behavior, a key indicator of pharmacological and dopaminergic activity in animals with induced brain lesions. The Rota-Count utilizes a flexible harness and tether system to accurately capture angular movement with high precision. The Rota-Count provides researchers with detailed data for both clockwise and counterclockwise rotations, offering a versatile tool for behavioral analysis.

Precise Rotational Tracking

The Rota-Count system uses a rotary encoder to measure full and partial rotations with 3.6-degree precision. It captures both clockwise and counterclockwise movements and allows users to define partial rotations from 15 to 180 degrees, allowing for tailored analysis of subtle movements.

Flexible Multi-Subject Monitoring

The Rota-Count is designed to monitor up to 32 subjects simultaneously, with each unit capable of handling 8 subjects. This multi-station setup makes it an efficient tool for large-scale experiments, allowing researchers to track multiple animals in parallel. The system’s flexibility extends to its setup options, with sensors that can be mounted on custom cages for specific research needs. Different sized harnesses are available to accommodate multiple subject sizes.
