BakerRisk proposes to use their extensive experience with shock testing, pressure transducers, and accelerometers, along with expertise in animal testing and the study of traumatic brain injury provided by their collaborator, Dr. David Cook, to produce a biomechanical surrogate of a rat. This device will stand in for the animal specimen in a variety of laboratory and in the field tests, recording pressures and accelerations. This will allow for the quantitative comparison and correlation of a wide range of experiments, thereby improving the ability of researchers to draw substantive conclusions and make advancements in the study of blast induced neurotrauma.
