DESCRIPTION:In nearly all of the contexts in biology in which groups of ci
 lia or flagella are found they exhibit some form of synchronized behaviour
 . Since the experimental observations of Lord Rothschild in the late 1940s
  and G.I. Taylor&rsquo\;s celebrated waving-sheet model\, it has been a wo
 rking hypothesis that synchrony is due in large part to hydrodynamic inter
 actions between beating filaments. But it is only in the last few years th
 at suitable methods have been developed to test this hypothesis.  Those me
 thods have led to the discovery of significant intrinsic biochemical noise
  in the beating of eukaryotic flagella.  This stochasticity occurs at the 
 level of individual beats\, with interesting variations within the cycle\,
  and is correlated and even recurrent\, with memory extending to hundreds 
 of beats.  Possible biological origins of this behaviour will be discussed
 .
