Full-Body Coordination in Mice During Tactile Exploration


Active sensing is the process by which organisms selectively extract information from their environment through actions such as eye motions, sniffing, or body motions like finger scanning. This project explored full-body coordination in mice during whisker-based tactile exploration, a key example of active sensing. Videos of mice searching for randomly located water rewards were analyzed using DeepLabCut (DLC), an open-source machine learning application for pose estimation. In ongoing analysis, we are investigating if detection of tactile contacts, or changes in head and body trajectories, are influenced by the timing of foot placement. Better understanding of motor coordination during tactile exploration could inform future treatments for sensory impairments and the development of technologies such as haptic interfaces.
