The Green’s function constructed by a number of methods. The voltage traces show the analytical solutions $G_{ij}(x,y,t)$ for fixed x and y on a binary tree for the length-priority method (red circles), the Monte-Carlo method (blue diamonds) and the matrix method with $k_{\max }=100$ (green squares) superimposed on NEURON’s numerical solution (black line). Parameter set A (Table 1) is used in these computations
