Neuromodulation and flexibility in Central Pattern Generator networks.
Central Pattern Generator (CPG) networks, which organize rhythmic movements, have long served as models for neural network organization. Modulatory inputs are essential components of CPG function: neuromodulators set the parameters of CPG neurons and synapses to render the networks functional. Each modulator acts on the network by many effects which may oppose one another; this may serve to sta...
متن کاملComparison of extrinsic and intrinsic neuromodulation in two central pattern generator circuits in invertebrates.
There are many sources of modulatory input to CPGs and other types of neuronal circuits. These inputs can change the properties of cells and synapses and dramatically alter the production of motor patterns. Sometimes this enables the production of motor patterns by the circuit. At other times, the modulation allows alternate motor patterns to be produced by a single circuit. Modulatory neurones...
متن کاملRemoval of spike frequency adaptation via neuromodulation intrinsic to the Tritonia escape swim central pattern generator.
For the mollusc Tritonia diomedea to generate its escape swim motor pattern, interneuron C2, a crucial member of the central pattern generator (CPG) for this rhythmic behavior, must fire repetitive bursts of action potentials. Yet, before swimming, repeated depolarizing current pulses injected into C2 at periods similar those in the swim motor program are incapable of mimicking the firing rate ...
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 کاملWalking Pattern Generator Using an Evolutionary Central Pattern Generator
For the generation of locomotion, such as walking, running or swimming, vertebrate and invertebrate animals use the Central Pattern Generator (CPG). In this paper, a walking pattern generator is proposed using an evolutionary optimized CPG. Sensory feedback pathways in CPG are proposed, which uses Force Sensing Resistor (FSR) signals. For the optimization of CPG parameters, quantuminspired evol...
