A neuron with label <math>j</math> receiving an input <math>p_j(t)</math> from predecessor neurons consists of the following components:<ref name=Zell1994ch5.2 />
A neuron with label <math>i</math> receiving an input <math>p_j(t)</math> from predecessor neurons consists of the following components:
