Modulated excitability: a new way to obtain bursting neurons.
Classical burster models are based on a fast system that either oscillates or is quiescent, depending on temporarily fixed values of slow variables. In a study of the lobster heart ganglion, we found a new type of burster for which the fast system is globally stable for all relevant fixed values of the slow variables. We describe how this burster works and speculate on its biological significance.
