Fig. 1.

Example of a toy neuron to demonstrate our labeling scheme. Branches are indexed using the Hines ordering (Hines, 1984), and junctions are labeled with italics. For this cell there are D = 3 dendrites and J = 4 junctions. Our labeling scheme implies, for example, that at junction 3 the children are indexed by $b_3^1=5,b_3^2=6$ and the mother is indexed by $b_3^3=8$
