On Hackaday, Richard Warren of the Sawtell Lab at Columbia University has shared his design for KineMouse Wheel, a light-weight running wheel for head-fixed locomotion that allows for 3D positioning of mice with a single camera.
Locomotive behavior is a common behavioral readout used in neuroscience research, and running wheels are a great tool for assessing motor function in head-fixed mice. KineMouse Wheel takes this tool a step further. Constructed out of light-weight, transparent polycarbonate with an angled mirror mounted inside, this innovative device allows for a single camera to capture two views of locomotion simultaneously. When combined with DeepLabCut, a deep-learning tracking software, head-fixed mice locomotion can be captured in three dimensions allowing for a more complete assessment of motor behavior. This wheel can also be further customized to fit the needs of a lab by using different materials for the build. More details about the KineMouse Wheel are available at hackaday.io, in addition to a full list of parts and build instructions.
