The Columbus Instruments Mouse Home Cage Running Wheel measures spontaneous activity in a voluntary free-spinning running wheel. The wheel is constructed to fit universally into most typical "shoebox" style cages (cage is not included with the system). Each wheel has a magnetic indicator and a hall effect sensor that connects to a computer interface and records wheel revolutions at user-specified intervals. Windows software is included for installation on a customer supplied PC. Data can be viewed in real time and exported into a CSV format at the end of the experiment.
The wheel is designed to fit universally into most home cages provided that the wire lid has a flat area measuring 2 inches (5.1 cm) x 4 inches (10.2 cm) and has a ceiling height of 5.5 inches (14 cm). The Wheel Counter Interface has inputs for 8 wheel sensors and multiple counters can be daisy chained together to provide a maximum of 128 wheel inputs.
