...Julia Machon; Juliette Ravaux; Magali Zbinden; Philippe Lucas ABSTRACT Antennular chemoreception in aquatic decapods is well studied via the recording of single chemoreceptor neuron activity in the antennule, but global responses of the antennule (or antennae in insects) by electroantennography...

... of highly sensitive, inherently noisy sensors. antennule behavior Crustacea * Author for correspondence ( [email protected] ) 10 1 2012 © 2012. 2012 Almost without exception, decapod and stomatopod crustaceans engage in antennular flicking, a behavior that theoretically...

...Matthew A. Reidenbach; M. A. R. Koehl SUMMARY Odors are dispersed across aquatic habitats by turbulent water flow as filamentous, intermittent plumes. Many crustaceans sniff (take discrete samples of ambient water and the odors it carries) by flicking their olfactory antennules. We used planar...

... of the antennules, between the flagellum and the brain, is somewhat higher than the corresponding conduction velocity of the same axons in the flagellum, especially for those whose flagellar conduction velocity is between 1 and 3 m s –1 , even though there is no net change in axonal diameter within this part...

... antennule of the spiny lobster, Panulirus argus , as a system to study how the morphology, orientation, and motion of sensilla-bearing appendages affects the small-scale water flow within the hair array. We tested whether antennule flicking enables lobsters to take discrete odor samples by measuring flow...

... of Biologists Limited 2007 2007 crustacean antennule hydrodynamic In aquatic as well as terrestrial environments, odors are dispersed primarily by advection and eddy turbulence, with passive diffusion playing only a minor role ( Dusenberry,1992 ). Information about local fluid movements is thus...

... of the response sequence. Odorant pulses seamlessly imbedded in the water pulse past the antennule evoked purely excitatory, dose-dependent postsynaptic responses and associated spike trains. The latency of the initial phase of the response to water was approximately half as long as the latency of the response...

...Manfred Schmidt; Charles D. Derby SUMMARY In the spiny lobster Panulirus argus the antennules carrying olfactory sensilla called aesthetascs and several types of other non-olfactory sensilla accompanying them are frequently groomed by the third maxillipeds in a stereotyped behavioral pattern...

...J. A. Goldman; S. N. Patek SUMMARY Most studies of lobster chemoreception have focused on the model systems of Panulirus argus (Palinuridae) and Homarus americanus (Nephropidae). We compare antennule morphology across lobsters and conduct the first kinematic study of antennule flicking...
