From: Multi-scale measurement of stiffness in the developing ferret brain
Comparison of rheometric and AFM measures of developing brain stiffness reveal disparity between bulk and microscale tissue development. (A) Comparison of mean Young’s moduli measured (AFM) or estimated from shear modulus (rheometry) in specific animals used for both AFM and rheometry experiments. Each data point represents the average value for one animal. Fitted lines are generated from a linear mixed-effects model. P-values are indicated on the left-hand side of the plot, comparing AFM to the corresponding rheometric test. (B) Estimates of shear modulus at 0% compression estimated by linear regression model from measured moduli at 4%, 8%, and 12% compression, with AFM. Each data point represents the average value for one animal.
