Constructor Summary

ShortTermPlasticitySynapse()
Default constructor needed for external calls which create neurons then set their parameters.

ShortTermPlasticitySynapse(Neuron source, Neuron target)
Creates a weight connecting source and target neurons.

ShortTermPlasticitySynapse(Neuron src, Neuron tar, double val, String theId)
Creates a weight of some value connecting two neurons.

ShortTermPlasticitySynapse(Synapse s)
This constructor is used when creating a neuron of one type from another neuron of another type Only values common to different types of neuron are copied.
