Using ${it Caenorhabditis elegans}$ as a model multicellular organism, we push forward a heavy-ion microbeam irradiation individual-study. As for about 1.2 mm in a range of carbon ions in water, all cells and tissues of ${it C. elegans}$ are microbeam irradiation objects. Sugimoto et al. showed DNA-damage-induced cell cycle arrest and apoptosis in locally irradiated areas of ${it C. elegans}$. We focus the nervous system of ${it C. elegans}$ and study the effects of localized irradiation on salt chemotaxis learning behavior. However, the anesthetic method for fixation of animals is not usable because the whole body irradiation of $$^{60}$$Co $$gamma$$ rays affected only transition stage of the conditioning for salt chemotaxis learning. Thus, now we are constructing the heavy-ion microbeam irradiation system for living target ${it C. elegans}$.

We reported an IR-induced reduction of locomotory rate of ${it Caenorhabditis elegans}$ in the absence of food. In the previous experiments, wild-type animals were irradiated with $$gamma$$-rays in the whole body, and measured the motility using "body bends" (the number of bends in the anterior body region at 20-s intervals). However, the IR-induced effects in the central and posterior body region were not evaluated by the body bends. In the present study, to investigate the IR-induced effects in more detail, we propose a novel method to evaluate the motility of the whole body using the video-based analysis.
