Modeling the gastric mill central pattern generator of the lobster with a relaxation-oscillator network.
1. The gastric mill central pattern generator (CPG) controls the chewing movements of teeth in the gastric mill of the lobster. This CPG has been extensively studied, but the precise mechanism underlying pattern generation is not well understood. The goal of this research was to develop a simplified model that captures the principle, biologically significant features of this CPG. We introduce a...
متن کاملNeuromodulation of the crab pyloric central pattern generator by serotonergic/cholinergic proprioceptive afferents.
In the stomatogastric nervous system of the crab, Cancer borealis, a set of 4 serotonergic/cholinergic proprioceptive neurons, called gastropyloric receptor (GPR) cells, have effects on the pyloric motor pattern. In a semi-intact foregut preparation, the GPR cells are not activated by movements of the pyloric filter; instead they respond to the slower movements of the gastric mill (Katz et al.,...
متن کاملGlutamate-gated inhibitory currents of central pattern generator neurons in the lobster stomatogastric ganglion.
Inhibitory glutamatergic neurotransmission is an elemental "building block" of the oscillatory networks within the crustacean stomatogastric ganglion (STG). This study constitutes the initial characterization of glutamatergic currents in isolated STG neurons in primary culture. Superfusion of 1 mM L-glutamate evoked a current response in 45 of 65 neurons examined. The evoked current incorporate...
متن کاملA model of the leech segmental swim central pattern generator
We present a model of the single-ganglion oscillator of the leech swim central pattern generator (CPG). The model is based on the known neuronal architecture of this circuit. Free parameters in the model were "tted to produce membrane potential oscillations matching those seen during swimming. However, the oscillations produced are not robust to small ($5%) changes in the parameters. We propose...
متن کاملVoltage-dependent switching of sensorimotor integration by a lobster central pattern generator.
Behavioral adaptations and the underlying neural plasticity may not simply result from peripheral information conveyed by sensory inputs. Central neuronal networks often spontaneously generate neuronal activity patterns that may also contribute to sensorimotor integration and behavioral adaptations. The present study explored a novel form of sensory-induced plasticity by which the resulting cha...
