Before revision:  Here we analyze the dynamics of heterogeneous populations of quadratic integrate-and-fire (QIF) neurons with both chemical and electrical coupling. To this aim, we derive an exact firing rate model that describes the collective dynamics of the QIF network in a unified framework valid for both electrical and chemical coupling.
