Synapse Model | NeuroDynamix II: Concepts of Neurophysiology ...
网页The Synapse model simulates the membrane potentials of three-compartment invertebrate neurons, comprising a soma, the neurite, and an axon. This model includes synaptic conductances to simulate synaptic interactions between neurons and thus can be used to simulate simple circuits as well as synaptic interactions between pairs of neurons.
