Title: Chemosensitive movement of cells

Abstract:
A widespread phenomenon in moving microorganisms and cells is their ability to orient themselves in dependence of chemical signals. During the talk kinetic models for chemosensitive movement are discussed which take into account different evaluations of the signal which subsequently influence the motion of the microbiological species. From the macroscopic point of view some types of evaluations of the chemical signal result in a change of the classical Keller-Segel models for chemotaxis. In the second part results on pattern formation in Keller-Segel type of models are discussed.
