Characterization of a Ferret Model of Traumatic Brain Injury due to Under-Vehicle Blast, Controlled Cortical Impact, or Blast Plus Impact.

ABSTRACT: Under-vehicle blast (UVB) generated from landmines is a unique traumatic brain injury (TBI) mechanism affecting warfighters. UVB hyperacceleration can result in injury independent of impact; however, a secondary impact injury can also occur. To date, translation of findings from rodent TBI models to improved patient outcomes has been unsuccessful, perhaps due to neuroanatomical differences between humans and rodents, including white-to-gray matter ratio and cortical gyrification. To address this modeling difference, a UVB model was developed in ferrets, the brains of which more closely resemble humans. Male ferrets underwent UVB-alone (Blast), controlled cortical impact (CCI)-alone, combined UVB + CCI (BCCI), or craniotomy (Sham) procedures. Neurobehavioral assays were optimized and used t
