The Opto-M4 is the latest advancement in Columbus Instruments' widely used multi-channel activity monitors. Frequently paired with the Oxymax-CLAMS for indirect calorimetry and activity measurement, the Opto-M4 can also function as a standalone system for precise position tracking. Its versatile applications span multiple research fields, including behavioral analysis, pharmacological studies, neuroscience, and cognitive testing.

Precise Position Tracking

The Opto-M4 utilizes an array of infrared beams to monitor animal movement with precision in real time. As subjects navigate their environment, the system detects beam interruptions and translates them into accurate data on both ambulatory and total movement. Additionally, the system can capture sleeping bouts when the subjects are stationary, providing a comprehensive overview of their activity patterns.

Flexible Sensor Configurations

The Opto-M4 offers unparalleled flexibility by allowing researchers to re-arrange sensor arrays based on their experimental needs. Whether it is a 20-cage X-axis-only setup or a 10-cage X and Z axes configuration, the system can be readily customizable. This capability maximizes the coverage and measurement precision for a variety of cage sizes and setups. Additional sensors and brackets can be purchased to expand the system further, offering a scalable solution for growing research needs.

Efficient Connectivity and Software

The Opto-M4 features interconnected emitters and detectors, with the controller delivering power directly through the signal cables, removing the need for external power supplies. Communication is efficiently managed via serial connections, ensuring compatibility with CI-Link software. This software empowers researchers to differentiate between subject movement, mask specific beam breaks, and export axis parameters for in-depth analysis.
