Source: Macheda, T., et. al. Electromagnetic Controlled Closed-Head Model of Mild Traumatic Brain Injury in Mice. J. Vis. Exp. (2022)This video demonstrates the procedure to induce a closed-head injury in a mouse model using a stereotaxic frame. The controlled impact replicates mild traumatic brain injury, allowing researchers to study neurological effects and recovery by measuring post-injury reflexes and behavior.

This video demonstrates the induction of traumatic brain injury (TBI) in a rat using a lateral fluid percussion injury (FPI) device. The procedure involves creating a hole in the skull of an anesthetized rat to expose the dura mater, onto which a cannula is attached. The rat is then connected to the device, which generates a pressure wave that reaches the brain, mimicking TBI by causing neural cell death and vascular...

Athletes absorb several hundred mild traumatic brain injuries (mTBI)/concussions every year; however, the consequence of these on the brain is poorly understood. Therefore, an animal model of single and repetitive mTBI that consistently replicates clinically relevant symptoms provides the means to advance the study of mTBI and concussion.

Lateral fluid percussion (LFP), an established model of traumatic brain injury in mice, is demonstrated. LFP fulfills three major criteria for animal models: validity, reliability and clinical relevance. The procedure, consisting of surgical craniotomy, fixation of hub followed by induction of injury, resulting in focal and diffuse injuries, is described.

This video demonstrates the delivery of Traumatic Brain Injury (TBI) in mice. After exposing the skull, the TBI site is marked. The mouse is then positioned under the TBI device. The impact is delivered by lifting the metal rod and allowing it to drop freely onto the impactor, which is in contact with the skull.
FAQs
The initial mechanical or ischemic insult can be followed by blood–brain barrier disruption, inflammation, and additional neuronal damage. This progression allows researchers to examine how early tissue deformation develops into later cellular and functional consequences. Tracking injury progression is important for identifying mechanisms that may be associated with neural repair or targeted by neuroprotective treatments.
Controlled cortical impact and fluid percussion provide calibrated mechanical challenges that can produce defined injury conditions. Their standardized application helps researchers relate the imposed injury severity to changes in neural tissue, behavior, inflammation, and barrier integrity. This connection supports comparisons across experiments while allowing investigators to study how traumatic forces influence subsequent brain responses.
The calibration of the applied force is central to defining injury severity and improving consistency between experimental groups. Severity can then be examined through behavioral and cellular outcomes, along with changes such as neuronal damage, inflammation, and blood–brain barrier disruption. Linking these measurements helps researchers interpret how injury intensity affects progression and recovery-related findings.
A study generally establishes a defined injury condition, applies a calibrated mechanical challenge using an appropriate induction method, and evaluates the resulting response. Researchers can then examine injury progression through behavioral and cellular measurements. Maintaining standardized induction and assessment conditions is essential for comparing injury severity across experiments and for determining whether an intervention changes the observed outcome.
Researchers can apply a standardized injury condition before comparing treated and untreated experimental groups. Behavioral and cellular outcomes reveal whether the intervention is associated with reduced damage, altered inflammation, improved barrier-related effects, or other changes in injury progression. This design helps evaluate neuroprotective strategies under controlled conditions rather than relying only on observations from uninjured neural tissue.
These models connect a defined injury condition with functional and biological consequences, including behavioral changes, neuronal damage, inflammation, and blood–brain barrier disruption. They also support investigation of neural repair and allow findings to be compared across injury severities. Such information helps researchers relate cellular mechanisms to broader patterns of brain injury progression and clinically relevant questions.
