Figure Legend:
Example of experimental stress-relaxation load traces for three regions of the adult rat brain over the first 0.5 s (in gray) demonstrating the range of stiffness encountered along with calculated loads using the Prony series fits for each individual load curve (indicated in the legend). The inset shows the indenter displacement into the tissue as a function of time (equivalent to the indentation depth).

Average shear modulus at 10 ms (G10ms), 50 ms (G50ms), and 20 s (G20 s) after the start of indentation calculated from Prony series fits from each curve within each region of interest in the (a) P17 (n = 4–16 indentations per region), and (b) adult (n = 6–14 indentations per region) rat brain and the results of the post hoc tests on each region for (c) P17, and (d) adult rat (error bars represent standard error of the mean; *, p < 0.05; **, p < 0.01)

Prony series model fits for all regions of the (a) P17, and (b) adult rat brain. The inset shows the Kolmogorov–Smirnov comparisons of the Prony series fits for each region (*, p < 0.05).
