.... Deflection-induced excitation of balancers in whole Mnemiopsis leidyi larvae and dissected adult (Mnemiopsis leidyi, Pleurobrachia pileus) statocysts was reversibly inhibited by the Ca 2+ channel inhibitors Co 2+ , Mg 2+ , Ni 2+ and Mn 2+ . Deflection-induced excitation in balancers of isolated adult M...

...David Barlow; Michael A. Sleigh ABSTRACT Parameters of ciliary beating and water propulsion can be studied in a unique fashion in ctenophores because the beat frequency can be controlled. Pleurobrachia pileus comb plates were driven at frequencies between 2 and 25Hz and at temperatures between 10...

...David Barlow; Michael A. Sleigh; Richard J. White ABSTRACT Patterns of water flow around steadily beating comb plates of Pleurobrachia pileus were tracked using suspended plastic beads. The positions of the beads and the comb plates in the plane of the central longitudinal axis of the comb row were...
