Traumatic brain injury (TBI) is a heterogeneous brain injury which represents one of the leading causes of mortality and disability worldwide. Rodent TBI models are helpful to examine the cellular and molecular mechanisms after injury. Controlled cortical impact (CCI) is one of the most commonly used TBI models in rats and mice, based on its consistency of injury and ease of implementation. Here, we describe a CCI protocol to induce a moderate contusion to the somatosensory motor cortex. We provide additional protocols for monitoring animals after CCI induction.

UI MeSH Term Description Entries
D001930 Brain Injuries Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.
