The average G moduli as a function of frequency f varying from 1 to 35Hz for (a) fibroblasts G ' –●, G " –○; (b) astrocytes G ' –▲, G " –Δ and (c) neurons G ' –♦, G " –◊. The experimental values were fitted using the structural damping law (solid line). G ' and G " both grow according to a power law with exponents γ = 0.22 ± 0.04 for fibroblasts, γ = 0.26 ± 0.04 for neurons and γ = 0.32 ± 0.04 for astrocytes
