 abstract = {We present a generic theory for the dynamics of a stiff filament under
tension, in an active medium with orientational correlations, such as a
microtubule in contractile actin. In sharp contrast to the case of a
passive medium, we find the filament can stiffen, and possibly oscillate
or buckle, depending on both the contractile or tensile nature of the
activity and the filament-medium anchoring interaction. We also
demonstrate a strong violation of the fluctuation-dissipation (FD)
relation in the effective dynamics of the filament, including a negative
FD ratio. Our approach is also of relevance to the dynamics of axons,
and our model equations bear a remarkable formal similarity to those in
recent work [Martin P, Hudspeth AJ, Juelicher F (2001) Proc Natl Acad
Sci USA 98: 14380-14385] on auditory hair cells. Detailed tests of our
predictions can be made by using a single filament in actomyosin
extracts or bacterial suspensions.},
