/* topo05.hoc

Model for HVC(RA) projection neuron with unmyelinated axon.
Simple ball and stick model of axon and soma.  The axon
has two types of sections one contains a mitodondrion and the other does not.
The section with the mitochondrion has increased intracellular resisitivity.
The length of a mitochondrion containing section is fixed at 1 micron. The
mitochondria containing sections are distributed uniformly along the axon.

This file sets the topological parameters to create an axon with 5%
longitudinal mitochondial coverage, that is 5% of the length of the axon
is made up of sections containing mitochondria. The length of an axon + a mitocondrion
section is 20 microns.
