Collective effects in ciliar arrays — •Andrey Ryskin and Peter Lenz — Fachbereich Physik, Philipps-Universität Marburg, D-35032 Marburg

Collective effects in ciliar arrays are studied analytically and numerically. A new phase oscillator description for ciliar motion is introduced which depends only on a single parameter. It allows to systematically study hydrodynamic interactions between cilia exhibiting arbitrary beating patterns. It is shown that under suitable conditions hydrodynamic interactions lead to synchronization of ciliar beating and formation of metachronal waves. The stability of these dynamical states is discussed.
