Physiological Insights from Cellular and Network Models of the Stomatogastric Nervous System of Lobsters and Crabs
Synopsis. The stomatogastric nervous system of decapod crustaceans is an ideal system for the study of the processes underlying the generation of rhythmic movements by the nervous system. In this chapter we review recent work that uses mathematical analyses and computer simulations to understand: 1) the role of individual currents in controlling the activity of neurons, and 2) the effects of el...
متن کاملUnderstanding circuit dynamics using the stomatogastric nervous system of lobsters and crabs.
Studies of the stomatogastric nervous systems of lobsters and crabs have led to numerous insights into the cellular and circuit mechanisms that generate rhythmic motor patterns. The small number of easily identifiable neurons allowed the establishment of connectivity diagrams among the neurons of the stomatogastric ganglion. We now know that (a) neuromodulatory substances reconfigure circuit dy...
متن کاملThe spatial and temporal patterns of odors sampled by lobsters and crabs in a turbulent plume.
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 laser-induced fluorescence to investigate how flicking antennules of different morphologies (long antennules of spiny lobsters, Panulirus argus; sho...
متن کاملMorphology of the Brain of Crayfish, Crabs, and Spiny Lobsters: A Common Nomenclature for Homologous Structures.
The morphologies of the cerebral ganglia (brains) of three infraorders of the decapod crustaceans (Astacura-crayfish; Brachyura-crabs; Palinura-spiny lobsters) are described. A common nomenclature is proposed for homologous nerve roots, brain regions, tracts, commissures, neuropils, and cell body clusters.
متن کاملMilky hemolymph syndrome (MHS) in spiny lobsters, penaeid shrimp and crabs.
Black tiger shrimp Penaeus monodon, European shore crab Carcinus maenas and spiny lobster Panulirus spp. can be affected by milky hemolymph syndrome (MHS). Four rickettsia-like bacteria (RLB) isolates of MHS originating from 5 geographical areas have been identified to date. The histopathology of the disease was characterized and a multiplex PCR assay was developed for detection of the 4 bacter...
