Slide 12

Computational model of the axonal arbor of a cortical pyramidal cell demonstrates that a significant portion is electronically close to the soma

Figure 12. Calculation of the length constant of a model cortical neuron.  The red line is the length constant of the axon for a "slice" like neuron - meaning with a reduced axon arbor similar to cells in the slice.  The blue line is the length constant of the same neuron with the full axonal arbor reinstated.  Both have relatively long axonal length constants.
