Abstract
The axial resistivity, Ri, is a measure of the Ohmic resistance of the intracellular medium of a neuronal process (e.g., axon or dendrite). Ri is defined as the resistance of the medium contained within a fixed-radius cylinder of unit length and unit cross-sectional area, measured between the flat ends of the cylinder. The most commonly used units are Ohm.cm, in which case the dimensions of the cylinder are in cm. For neurons, Ri is typically on the order of 100 Ohm.cm.
