An animal’s level of general activity or locomotion is an indicator of drug action, toxic substances, neurological damage, or daily rhythms in activity. Activity data may be automatically and unobtrusively collected by many methods.
The electronic unit used by the Infrared Array cages includes a thermal printer, data display, and RS 232 serial port for interface to any computer. The 4 variable function keys below the display may be used to enter animal and experiment numbers, gender, etc., which will be passed to the computer with the numerical data. Windows® software for data collection is available (WinDas Software).
Two models of the Data Controller are available, one accepting a single cage, and the other accepting connections for up to six cage units. Both are housed in an attractive cylindrical chassis that allows the graphic LCD display to be tilted to any viewing angle convenient to the operator.
The 57420 is a complete single-cage setup for activity monitoring by infrared beams, including the cage and the electronic unit and cable.
The 57445 is a system for up to 6 cages, but includes only one cage. Additional cages fitted with IR arrays (No. 57433) may be ordered as needed.
Infrared Beam Break Monitor
As the animal moves about a clear acrylic cage, it interrupts one or more infrared beams. The beams are arranged in an array of emitters on one side of the cage, detectors on another. The lower IR array monitors horizontal movement while the upper IR array monitors vertical or rearing activity. The number of beam breaks is correlated with the amount of movement about the cage.
