Axonal viscosity increases during aging. A. Axonal viscosity (G) which is an aggregate measure of axonal diameter and intrinsic viscosity (g) increased as a function of age and was significantly different between all groups. B. Axonal diameter decreased as a function of age. C. The intrinsic viscosity (g), increased significantly with aging. D. The strength of adhesions (η) was similar in neurons from neonatal and adults. For all graphs, the average +/- 95% CI is shown and the number of measurements is listed above the bars.
