Blast-shock waves cause mild to moderate to severe blast induced neurotrauma (BINT) in acute and chronic stages. The basic mechanics of shock-(bio) structure interaction and the mechanisms of damage are not known. To understand the interaction of blast on the head\/brain complex; to identify the mechanisms of injury; to examine the role of protective systems on injury; to provide better diagnostic, prognostic and therapeutic tools, shock tubes are extensively used in the laboratory to simulate the field conditions. By detailing the results from a series of careful experiments (field explosions and shock tubes) and numerical simulations, we demonstrate that 1) blast profiles continuously evolve along the length of the tube, \u0026nbsp;2) blast tubes can replicate primary field conditions in a narrow test region 4) shock-blast waves interact with structural and biological media very differently, \u0026nbsp;5) helmet material and geometry play a critical role in protecting or otherwise, \u0026nbsp;and 6) studies using animal models\/cadavers\/test dummies\/single neurons provide great insight into the biomechanical loadings and post-injury biochemical and pathophysiological (e.g. break down of blood-brain barrier, neuronal plasma damage) sequelae.
