Abstract

The pia arachnoid complex (PAC) is a cerebrospinal fluid-filled tissue that surrounds the brain and spinal cord. Within the PAC, arachnoid trabeculae (AT) fibers, AT sheets, and blood vessels span the space between the arachnoid and pial surfaces. These microstructures help hold the delicate central nervous system tissue in place [1]. Due to its structural role, alterations to the biomechanical properties of the PAC caused by sub-concussive hits could impact stresses acting on the brain during traumatic brain injury (TBI). Relatively few studies have investigated PAC biomechanics [2-4]. However, relatively little is known about PAC biomechanical properties causing a gap in knowledge making it difficult to accurately model TBI using finite element modeling (FEM) [5, 6]. The aim of this study was to quantify the mechanical and structural properties of ovine PAC.
