“…Experiments have considered brain tissue subjected to compression, tension, and shear (Bentil and Dupaix, 2014;Budday et al, 2017;Darvish and Crandall, 2001;Hrapko et al, 2006;Jin et al, 2013;Miller and Chinzei, 2002;Rashid et al, 2013;Velardi et al, 2006;Zhao et al, 2018). Challenges in investigating the properties of the brain are magnified by the heterogeneous and anisotropic nature of the tissue (Boudjema et al, 2015). Previous experiments have been conducted to investigate factors such as the brain's temperature, region (right vs. left hemisphere), and size (Boudjema et al, 2015;Budday et al, 2015Budday et al, , 2017Christ et al, 2010;Fallenstein et al, 1969;Jin et al, 2013;Prange and Margulies, 2002;Rashid et al, 2012b;Tirella et al, 2013;Velardi et al, 2006).…”

Traumatic brain injuries (TBI) affect millions of people each year and can result in long-term difficulties in thinking or focusing. Due to the number of people affected by these injuries, significant research has been dedicated to determining the mechanical properties of the brain using postmortem tissue from animals harvested within 24 hours. The postmortem brain tissue is often stored in a solution until a rheological experiment is ready to begin. However, the effect of storage duration on the mechanical behavior of brain tissue is not understood. In this paper, postmortem porcine brains were placed in normal saline solution (0.9% NaCl) and refrigerated between 30 minutes and 6.5 hours to allow the brain to absorb the solution. Afterwards, samples from both soaked and freshly extracted brains were subjected to unconfined compression tests at compressive rates of 5, 50, and 500 mm/min. The fractional Zener viscoelastic model was applied to obtain the brain's mechanical properties. While the results did not show a significant relationship between absorption and the long-term stiffness (E ∞ ), both the relaxation time (τ 0 ) and fractional order (α) were statistically influenced by both the length of time in the solution and compressive rate. Further, the instantaneous stiffness (E 0 ) was statistically influenced by the length of time in solution, though not the compressive rate.
