Dynamic Re-wiring of CPG Circuits in a Simple Nervous System

摘要: The pyloric CPG in the stomatogastric nervous system of crustaceans can produce a wide repertoire motor patterns, both vivo and vitro. This flexibility network operation, relies on endogenous properties shared by all neurons network, i.e. ability to bursting pacemaker potentials. These are controlled modulatory inputs. By inducing, modulating suppressing regenerative neurons, inputs start, maintain terminate basic pattern. They also transform this pattern changing period rhythm, phasing, duration intensity neuronal discharges, number active neurons. Finally, simultaneous modulation several networks create complex switch between two circuits fuse CPGs.
