"Dendritic electrical coupling increases the number of effective synaptic inputs
onto neurons by allowing the direct spread of synaptic potentials from one
neuron to another.
Here we studied the summation of excitatory postsynaptic potentials (EPSPs) produced
locally and arriving from the coupled neuron (transjunctional) in pairs of
electrically-coupled Retzius neurons of the leech.
We combined paired recordings of EPSPs, the production of artificial EPSPs
(APSPs) in neuron pairs with different coupling coefficients and simulations of
EPSPs produced in the coupled dendrites.
