Patterns of electrical activity in comb plates of feeding Pleurobrachia (Ctenophora)
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1993Abstract The electromotor behaviour of ciliary comb plates was studied during prey-stimulated and electrically stimulated feeding by intact Pleurobrachia pileus (Müller). Comb plate electrical activity was recorded by extracellular electrodes attached directly to the cilia; comb plate motility was recorded by high-speed video ...

The physiology of feeding in the ctenophore Pleurobrachia pileus
Hydrobiologia, 1991Ciliary organelles play important roles in many of the locomotory and sensory functions of ctenophores. This paper reviews published work on the physiology and behavior of ciliary-based feeding in Pleurobrachia pileus and presents recent preliminary work on the conduction pathway controlling this behavior.

Gene Expression Patterns in the Ctenophore Pleurobrachia bachei: In Situ Hybridization
In situ hybridization is a powerful and precise tool for revealing cell- and tissue-specific gene expression and a critical approach to validating single-cell RNA-seq (scRNA-seq). However, applying it to highly fragile animals such as ctenophores is challenging.Andrea B, Kohn +2 more

Seasonal occurrence of the ctenophore Pleurobrachia pileus in the western Dutch Wadden Sea
Marine Biology, 1984Due to the short residence time of the water in the western Dutch Wadden Sea the ctenophore Pleurobrachia pileus has to be considered as an allochthonous species, which enters the estuary passively from the North Sea. The seasonal occurrence of this species in the Dutch Wadden Sea is a reflection of its abundance in the coatal zone of the North Sea and

Effect of ctenophore predation on mesozooplankton during a spring outburst of Pleurobrachia pileus
Netherlands Journal of Sea Research, 1990A spring outburst of the ctenophore Pleurobrachia pileus in Dutch coastal waters was studied by almost daily sampling. Till the end of May, small ctenophores (

Intercellular gap junctions occur between the ciliated cells that make up the comb plates of the ctenophore Pleurobrachia. Similar junctions are found within the ciliated grooves which run from the apical organ to the first plate of each comb row, as well as throughout the endoderm of the meridional canals.

Unilateral Ciliary Reversal and Motor Responses During Prey Capture by the Ctenophore Pleurobrachia
Journal of Experimental Biology, 1985ABSTRACT High-speed cinematography of feeding Pleurobrachia revealed a stereotyped sequence of ciliary motor responses underlying the feeding behaviour of this ctenophore. Prey capture by a tentacle first elicited high frequency beating in all comb rows, propelling the animal forward at a rapid speed for several seconds.

Movements and Co-ordination of the Ciliary Comb Plates of the Ctenophores Beroe and Pleurobrachia
Nature, 1963INVESTIGATIONS by Afzelius1,2 on the comb plates of Mnemiopsis showed that these plates are compound structures built up from several hundred thousand cilia of somewhat modified structure, the shafts of which are apparently cemented together in long rows.

Metachronal Co-ordination of the Comb Plates of the Ctenophore Pleurobrachia
Journal of Experimental Biology, 1968ABSTRACT The activity of comb plates of Pleurobrachia was analysed from cine films. The interval between successive beats of a comb plate varied from several seconds to about 50 msec, in normal sea water; this variation in frequency was accompanied by a variation wave velocity.
