Electrical synaptic transmission and voltage-gated ionic currents are often studied independently from one another. This model allows to study the interactions between the hyperpolarization-activated inward ionic current and a rectifying electrical synapse. Two single compartment nonspiking neurons are coupled through a rectifying electrical synapse. Current pulses are applied into the presynaptic neuron. The amplitude of the electrical postsynaptic potentials is measured. Ih can be added to either the pre- or postsynaptic neuron, or both. The cells represent the the MCN1 and LG neurons in the crab stomatogastric ganglion.
