Clinically, traumatic brain injury (TBI) results in complex heterogeneous pathology that cannot be recapitulated in single pre-clinical animal model. Therefore, we focused on evaluating utility of nanoparticle (NP)-based therapeutics following three diffuse-TBI models: mildclosed-head injury (mCHI), repetitive-mCHI and midline-fluid percussion
