Abstract

We consider one prominent example for an active biological fluid, namely the cytoplasm of the true slime mold Physarum polycephalum. We model the cytoskeleton as a solid matrix that together with the cytosol as interstitial fluid constitutes an active poroelastic material and reproduce a large variety of experimentally observed mechanochemical wave forms, e. g. spirals, turbulence, target waves.

Keywords: physarum modelling active poroelastic mechanochemical waves
