Basic morphologies of axon affect EF firing threshold in artificial model. (a) and (b) give the EF threshold as a function of two types of bend angle θ and α. (c) and (d) show the field threshold as a function of branch angle β and branch number Nt of axon terminal. The diameter and length of each branch (indicated by red lines) in (b–d) are 2 μm and 20 μm, respectively. Other morphological and biophysical parameters of the artificial neuron are as described in Methods.
