Abstract : We use multiscale modeling and computational fluid dynamics to examine the stability of a swimming organism in the face of perturbations, with and without sensory feedback. We focus on the lamprey, the most basal living vertebrate, and hence a model organism for studying the neural control of locomotion. We investigate how the coupling among forces due to passive tissue properties, active muscular forces and the forces from the external fluid environment contribute to the dynamics and stability of swimming.
