• An Improved mathematical model simulating the movement of Dictyostelium discoideum slugs on a plane surface is presented and compared with the results obtained in vivo. The model allows the simulation of random movements under non-stimulated conditions and the oriented movement in the presence of photic, thermal and chemical stimuli. The simulation supports the hypothesis that the external stimuli are internally converted into a gradient of a low molecular weight substance in which the organisms orient chemotactically. A spatially defined field containing this substance is avoided by the organisms while a uniform background decreases the degree of orientation to a light stimulus both in vivo and in the simulation. The behavior observed in mutants can be simulated by adjusting the sensitivity coefficients in the simulation functions for the various stimuli.
