Comparative Analysis of Half-Center Central Pattern Generators (CPGs)
CPGs are networks of neurons that can produce rhythmic activity, featuring a stereotyped sequence of phases that repeats in a periodic-like manner, without receiving rhythmic inputs from an outside source. Half-center CPGs, also known as half-center oscillators, are CPGs consisting of two components connected by reciprocal synaptic inhibition. While the coupled network exhibits a two-phase pattern, with one component exhibiting a high activity level and the other at a low activity level in each phase, the individual components are not able to switch between sustained high and low activity phases in isolation. Comparative analysis of half-center CPGs is the study of how specific features of half-center CPGs translate into particular properties.
A half-center CPG consists of a pair of components and the coupling between them. Each component may be an individual neuron or a population of neurons. In a half-center oscillation, each component switches back...
