Figure 4.

Impact of a perturbation in M on fibrillization. During the perturbation time, t_pert, the number of microglia M is reduced 10-fold. F is depleted relative to its steady-state value before perturbation. The inset diagram on the left side shows the concentration of fAβ at the end of the perturbation period, F_pert. The inset diagram on the right side shows the recovery time, t_recov, as a function of the perturbation period. The perturbation time in the inset diagrams is plotted in the units of days. R = 1.2 × 10⁻³ = 0.92 R_c. To see this figure in color, go online.
