Figure 9.

Axon stretch versus time for n = 150 simulation with characteristic time constant of the cross-links, $\tau =100$s, and varying microtubule (de-)polymerization rates. The colored regions of each curve represent the regions that are used to compute average stretch rate and viscosity for that particular simulation. We only use time after $t=250$s to make sure the simulations have reached a steady state. In addition, we do not include sharp jumps in the axon stretch that are due to weak spots in the axon as a result of excessive microtubule depolymerization in a cross section of the axon.
