Motional barriers due to geometrical restrictions are ubiquitous in heterogeneous media such as porous rocks or biological tissues. As a consequence, molecular propagation deviates from the patterns of Gaussian diffusion. In this paper, we report on the results of the application of several non-Gaussian and anomalous diffusion models used to describe experimental data in the artificial anisotropic system with well-defined properties. In particular, we focus on the influence of fibre packing density on the quantitative metrics of these models and compare their sensitivity to this parameter. The results are discussed in the context of the importance for better understanding the governing diffusion mechanisms in complex tissue microstructures.
