ABSTRACT
Traumatic brain injury (TBI) is mainly due to automotive accidents, contact sports, falls or blunt impacts to the head. It has been shown that subarachnoid space (SAS) trabeculae play an important role in damping and reducing the relative movement of the brain with respect to the skull, thereby reducing traumatic brain injuries (TBI) (Zoghi-Moghadam and Sadegh, 2010). However, the histology, architecture and mechanical properties of the SAS are not well established in the literature. Previous investigators have oversimplified the complex architecture of the SAS trabeculae and have employed soft solid materials for the SAS, which may lead to unreliable results.
