This model simulates in retinal ganglion cells. It uses HH formalism and is capable of producing realistic firing properties in response to the constant depolarization. This is a single-compartment version of the model.

Abstract excerpt: "Experimental efforts were guided by computer simulation studies of an excitability model consisting of five voltage- or ion-gated channels, which were identified from earlier voltage-clamp data. The ion channels include sodium, calcium, and three types of potassium channels, namely the A type (IK,A), Ca-activated potassium (IK,Ca), and the delayed rectifier (IK). A leakage channel was included to preserve input resistance continuity between model and experiment."
