2025
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.

We present a user-friendly, high-throughput operant system for the evaluation of pain behaviors in awake, conscious rodents. The Orofacial Pain Assessment Device (OPAD) can assess pain through a reward/conflict paradigm thus providing a more humane way of testing. This protocol will yield more clinically relevant and translational data from rodents.

2025
The video demonstrates a method to generate a mouse model of traumatic brain injury (TBI) using a lateral fluid percussion device (LFPI). Upon anesthetizing the mouse, the brain is exposed by creating a window on the skull. A saline-filled cannula is attached to the window and is then connected to the LFPI. The pendulum of the device is released to create a pressure pulse that inflicts a traumatic brain injury.

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...
FAQs
Calibration links the device setting to the intended level of tissue damage. Researchers can regulate the applied force, pressure, impact, or displacement and then use standardized measurements to verify the resulting injury. This control helps separate effects caused by different injury severities from variation introduced by inconsistent device operation, strengthening comparisons across experimental groups.
Standardized settings reduce experimental variability by keeping the mechanical input consistent between samples or subjects. Greater consistency makes it easier to attribute differences in cellular damage, inflammation, circuit disruption, or recovery to the biological condition being studied rather than to unintended changes in the injury procedure. The approach therefore supports reproducible neuroscience experiments.
Some instruments create a controlled neural injury by applying a defined mechanical input, whereas others measure or assess the damage produced afterward. Keeping these functions conceptually separate helps researchers distinguish the experimental insult from its readouts. That distinction is useful when connecting the initial injury condition with structural, cellular, physiological, or behavioral consequences.
Researchers should control the type and magnitude of the applied input, the device settings, and the measurements used to characterize the resulting tissue damage. Force, pressure, impact, and displacement represent different ways to impose or describe mechanical injury. Consistent control and documentation of these factors improve interpretation of injury severity and experimental variability.
A general workflow includes selecting the intended injury condition, setting the device to deliver a calibrated force, pressure, impact, or displacement, applying the input to nervous tissue, and recording standardized measurements. Researchers then relate those measurements to biological and functional outcomes. The exact workflow depends on whether the instrument creates damage, assesses it, or supports both roles.
Researchers use these controlled procedures to investigate how neural tissue is damaged, how inflammation and circuit disruption develop, and how function changes during recovery. The resulting models can also support evaluation of potential treatments. By linking structural changes in the brain or spinal cord with behavioral and physiological outcomes, the approach connects tissue-level mechanisms to broader nervous-system function.
These models allow investigators to examine several levels of injury response, including cellular damage, inflammation, circuit disruption, and functional recovery. Measurements can be considered alongside structural changes in the brain or spinal cord and with behavioral or physiological outcomes. This combined perspective helps researchers evaluate how tissue injury relates to nervous-system performance and treatment effects.
