Traveling waves in a ring of three inhibitory coupled model neurons

The pyloric network of the stomatogastric ganglion of the lobster generates motor patterns with speciic phase-lags between single neurons. This network inspired us to investigate a simpliied model consisting of three mono-directionally coupled Morris-Lecar oscillators. We have systematically analyzed the high-dimensional space of the synaptic parameters and identiied parameter combinations which lead to biologically plausible phase-lags that exist even in a network with identical cells in the absence of an intrinsic burster. The dependence of the phase lags on the synaptic parameters was also explored.
