...C. Vanderlinden; J. Mallefet SUMMARY In ophiuroids, bioluminescence is under nervous control. Previous studies have shown that acetylcholine is the main neurotransmitter triggering light emission in Amphipholis squamata and Amphiura filiformis . By contrast, none of the neurotransmitters tested so...

...C. Vanderlinden; Y. Dewael; J. Mallefet SUMMARY We investigated the effects of cyclic nucleotides (cGMP and cAMP) and inositol triphosphate/diacylglycerol pathways on the KCl-induced luminescence control of the ophiuroid species Amphiura filiformis, Ophiopsila aranea and Ophiopsila californica...

...Y. Dewael; J. Mallefet SUMMARY Study of the control mechanisms of light emission in invertebrates shows the involvement of several neurotransmitters. In ophiuroids, only one species ( Amphipholis squamata ) has so far been characterized for luminescence control, which seems to be cholinergic...

...N. De Bremaeker; F. Baguet; M. C. Thorndyke; J. Mallefet ABSTRACT Amphipholis squamata is a polychromatic luminescent ophiuroid. The effects of amino acids ( γ-aminobutyric acid, GABA, taurine, glycine and glutamate), N -methyl-D-aspartate (NMDA) and the invertebrate neuropeptides Antho-RFamide...

... with an asteroid tubefoot secured to a hypodermic needle with fine thread. The needle was attached via a plastic rod to the movable breaker of a d.c. relay that could be activated with a toggle switch. The closing relay simultaneously moved the tubefoot several millimetres to hit the ophiuroid arm and triggered...
