During forward swimming, pairs of crayfish swimmerets (limbs) exhibit a robust pattern, moving rhythmically in a back to front metachronal wave with neighbors delayed by approximately 25% of the period. We study the mechanism responsible for this coordinated limb behavior using a model which represents the underlying neural circuitry as a chain of coupled oscillators. Previous modeling efforts have only considered the effects of nearest neighbor coupling, ignoring the presence of longer range connections in the system.

In this talk, we address how long-range coupling affects this mechanism, using an oscillator chain whose architecture reflects the known neural circuitry in the swimmeret system. Results from analytical arguments and numerical simulations indicate that long-range coupling tends to speed up the metachronal wave, and we suggest that this may maximize swimming efficiency.
