This video demonstrates the procedure for inducing traumatic brain injury (TBI) in a mouse model. An anesthetized mouse with an exposed skull is taken to create an opening in the skull, and then a controlled cortical injury is induced using an impact device. The injury damages the brain tissue, causing impaired cognitive function and motor coordination.

This video demonstrates the procedure for inducing an open-skull traumatic brain injury in a mouse by making a midline skull incision, drilling through the skull and removing the bone flap to expose the brain cortex, and applying high pressure to induce trauma. The wound is then sutured to prepare the mouse model for subsequent experiments.

FAQs
The computer coordinates the actuator so each impact follows programmed mechanical conditions rather than relying on variable manual delivery. Researchers can specify and reproduce impact velocity, deformation depth, and dwell time across experiments. This consistency helps establish comparable controlled cortical injuries, making differences in neurological damage, inflammation, functional deficits, or recovery easier to associate with the experimental conditions.
These parameters describe distinct features of the mechanical challenge delivered to tissue. Velocity establishes how rapidly the impact occurs, deformation depth specifies the extent of tissue displacement, and dwell time defines how long the actuator remains engaged. Controlling them separately gives researchers a defined injury model and supports meaningful comparisons among experiments using different conditions.
Computer control reduces variation in how injuries are produced, which strengthens interpretation of subsequent biological findings. When impact conditions remain consistent, observed changes in neurological damage, inflammation, functional deficits, or recovery can be compared more confidently between experimental groups. The controlled setup therefore connects an engineering measurement with medicine-focused analysis of injury mechanisms and treatment outcomes.
Its main advantage is standardized delivery of the mechanical event. By regulating actuator timing and measured impact variables, the system limits differences that could otherwise complicate comparisons between experiments. In traumatic brain injury research, improved reproducibility helps investigators distinguish effects associated with the injury model or a potential therapy from effects caused by inconsistent impact conditions.
A typical workflow establishes the intended impact conditions, programs the computer to direct the actuator, and delivers the impact to biological tissue under those defined settings. Researchers then examine the resulting controlled cortical injury for neurological damage, inflammation, functional deficits, and recovery. The same measured parameters can be retained across experiments to support reproducible testing.
Researchers would use it when they need a reproducible experimental model for studying traumatic brain injury and its consequences. The resulting injuries support investigation of damage mechanisms, inflammatory responses, neurological or functional deficits, and recovery. Because conditions are standardized, the system is also useful for comparing potential therapies and evaluating whether treatment outcomes remain consistent across experiments.
