“…20 mediated by GABA as Picrotoxin, a non competitive GABAergic antagonist, partially abolished the CIR already described in this decapod (Hermitte and Maldonado, 2006;Burnovicz et al, 2009;Burnovicz and Hermitte, 2010).…”

“…CIR has been associated both with attentional phenomena in vertebrates (Powell, 1994) and with the orienting response in invertebrates (Shuranova and Burmistrov, 1996). In addition, CIR has been described as a component of the "death-feigning behavior" in decapod crustaceans (McMahon and Wilkens, 1972) and as an index of sensory perception and evidence of a neuroautonomic response in the crab Neohelice granulata (Hermitte and Maldonado, 2006;Burnovicz et al, 2009;Burnovicz and Hermitte, 2010). In any case, its prevalence across invertebrates and vertebrates leads to the assumption that it has a universally adaptive function.…”

ABSTRACTThe aim of the present work is to provide an anatomical description of the cardiac system in the crab Neohelice granulata and evidence of the presence of GABA by means of immunohistochemistry. The ganglionic trunk was found lying on the inner surface of the heart's dorsal wall. After dissection, this structure appeared as a Y-shaped figure with its major axis perpendicular to the major axis of the heart. Inside the cardiac ganglion, we identified four large neurons of 63.7 µm ± 3.7 in maximum diameter, which were similar to the motor neurons described in other decapods. All the GABA-like immunoreactivity (GABAi) was observed as processes entering mainly the ganglionic trunk and branching in slender varicose fibers, forming a network around the large neurons suggesting that GABAi processes contact them.Our findings strengthen previous results suggesting that the GABAergic system mediates the cardioinhibitory response upon sensory stimulation.

Electrocardiography has been applied to examine the response of crab species to temperature, pressure (Mickel & Childress, 1982), visual stimulus (Grobel, 1990;Hermitte & Maldonado, 2006;Burnovicz, Oliva & Hermitte, 2009;Burnovicz & Hermitte, 2010), and chemical stimulus (Ketpadung & Tangkrockolan, 2006;Medesani et al, 2011).…”

Swimming crabs have a characteristic fifth pair of legs that are flattened into paddles for swimming purposes. The dactyl of these legs bears a thick seta along its edge. The chemoreceptive and feeding properties of the seta are supported with scientific evidence; however, there is no available data on the sensitivity of the setae in portunid crabs. The underlying mechanisms of the chemo- and mechano-sensitivity of appendages and their involvement in feeding activities of the mud crab (Scylla paramamosain) were investigated using electrocardiography and behavioural assay, which focused on the responses of the mud crab to chemical and touch stimulus. Electrocardiography revealed the sensory properties of the appendages. The dactyls of swimming legs and the antennules were chemosensitive, but not mechanosensitive and vice versa for the antennae. However, the mouthparts, claws, and walking legs were chemo- and mechanosensitive. Only the chemosensitive appendages, including the swimming legs, were directly involved in feeding. The flattened dactyls of the swimming legs were more efficient than the pointed dactyls of the walking legs in detecting the food organism crawling on the substrate. The structural features enhanced the capacity of the crab in coming into contact with scattered food items. This study revealed that the swimming legs are important appendages for feeding in the mud crab.
