Abstract
A model of locally pumped Brownian particles is developed which shows some basic features of animal motion. Moving through the active region the particles are pumped with high valued energy and are accelerated. In particular, the dynamics shows limit cycles which resemble tracks. As generalizations stochastic motion and reservoirs carried by the pa rticles are considered. A delay time between pumping with high-valued energy and acceleration is introduced.
