Controlled Cortical Impact in the Rat

Traumatic brain injury (TBI) is a major cause of death and disability world-wide. Following initial injury, TBI patients can face long-term disability in the form of cognitive, physical, and psychological deficits, depending on the severity and location of injury. This results in an economic burden in the United States estimated to be $60 billion due to health-care costs and loss of productivity. TBI is a significant area of active research interest for both military and civilian medicine. Numerous pre-clinical animal models of TBI are used to characterize the anatomical and physiological pathways involved and to evaluate therapeutic interventions. Due to its flexibility and scalability, controlled cortical impact (CCI) is one of the most commonly used preclinical TBI models.
