Parametric stability in a silicon model of the leech swim oscillator

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

In this study, parametric sensitivities of the leech swim network are characterized in a cell-by-cell model implemented in analog VLSI hardware. Each hemiganglion of the swim network contains eleven tonically active cells arranged in 34 distinct oscillator subnetworks. Initial circuit tests showed reciprocally inhibitory networks to be sensitive to synaptic fatigue and refractory period, yet immune to cell threshold, while cyclically inhibitory networks were found to be sensitive to cell threshold, yet immune to refractory period. In subsequent tests, a model of the entire hemiganglion was found to be significantly less sensitive to all parameters than either suboscillator type alone.
