ImageJ-based automatic motion tracking in aquatic amphibian

by Loïc Grattier - published on

Motor behavior studies require the technical capacity to track automatically characteristic body points in motion using a high frequency rate video recording. Online or commercial motion capture systems based on target detection are now quite efficient to track body joints in movements for terrestrial subjects like rodents or humans. However it remains particularly difficult to assess the same work on aquatic animals like fishes or amphibian due to the water environment constrains. Since 2015 Gilles Courtand is developing a series of ImageJ based programs allowing frame-by-frame offline video tracking of typical regions of interest in larval and juvenile amphibians (Xenopus sp). This panel of application enables to quantify motion behaviors such as binocular compensatory eye movements generated by feedback and feedforward sensory-motor reflexes or tail/limb locomotor kinematic during free swimming episodes. These tools have been already used to achieve a recent study on locomotor-driven eye movements in metamorphosing frog (coming soon on INCIA news).
