Amoeboid movement as a correlated walk.

Abstract

The movement of slime-mold amoebae under isotropic conditions in two dimensions is represented as a Correlated Walk with straight steps of variable length. The steps are correlated via the angle theta turned through from step to step. The hypotheses and predictions of the model compare favourably with experimental data for Dictyostelium discoideum amoebae.
