SUMMARY:Synchronisation of eukaryotic flagella - Marco Polin (DAMTP)

DESCRIPTION:From unicellular organisms as small as a few microns to the la
 rgest vertebrates on earth we find groups of beating flagella or cilia tha
 t exhibit striking spatio-temporal organization. This may take the form of
  precise frequency and phase locking as frequently found in the swimming o
 f green algae\, or beating with long-wavelength phase modulations known as
  metachronal waves\, seen in ciliates such as Paramecium and in our own re
 spiratory systems. The remarkable similarity in the underlying molecular s
 tructure of flagella across the whole eukaryotic world leads naturally to 
 the hypothesis that a similarly universal mechanism might be responsible f
 or synchronization. Although this mechanism is poorly understood\, one app
 ealing hypothesis is that it results from hydrodynamic interactions betwee
 n flagella. In this lecture I will discuss recent results using green alga
 e as model organisms which provide the strongest evidence yet for the elas
 tohydrodynamic origin of synchronisation.\n
