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.

A multi-faceted approach to investigating functional changes to hippocampal circuitry is explained. Electrophysiological techniques are described along with the injury protocol, behavioral testing and regional dissection method. The combination of these techniques can be applied in similar fashion for other brain regions and scientific questions.

(2020)This video demonstrates the induction of closed-head mild traumatic brain injury in a mouse model using a pressurized gas shock tube setup. The generated pressure wave ruptures the polyester membrane, delivering a shockwave to the mouse’s head that results in rapid brain movement within the skull, causing a mild traumatic brain injury.

FAQs
The injury can disturb neuronal membranes, alter signaling, and weaken communication across brain networks even when routine imaging shows no visible abnormality. These functional changes help explain why a person may experience headache, dizziness, memory difficulty, or altered attention without a clearly detectable lesion. Neuroscience research therefore examines both cellular signaling and network connectivity, not only structural damage.
Rapid acceleration or deceleration can expose the brain to mechanical forces that disturb neuronal membranes and signaling. The resulting dysfunction may affect several neurological domains, including attention, memory, balance, and physical comfort. Focusing on the force pattern helps neuroscience researchers connect the circumstances of injury with symptom development, functional disruption, and differences in recovery.
Normal routine imaging does not necessarily exclude meaningful neurological dysfunction because mTBI may alter cellular processes and network connectivity without producing visible structural damage. This limitation is important in clinical interpretation: symptoms and functional assessments remain relevant even when scans appear normal. Advanced imaging is also being studied as a way to investigate changes that routine methods may not reveal.
Research examines disrupted neuronal membranes, altered signaling, and changes in network connectivity alongside symptoms such as headache, dizziness, memory difficulty, and altered attention. These investigations seek to relate underlying brain dysfunction to observed behavior and experience. The broader goal is to identify biomarkers and clarify why some effects resolve while cognitive, emotional, or physical problems may persist.
Clinical evaluation can combine symptom review with neurological assessment, symptom monitoring, and neuropsychological testing. Neuropsychological measures help examine functions such as memory and attention, while ongoing monitoring tracks how symptoms change over time. Using multiple sources of information provides a broader picture of functional status than relying on routine imaging alone.
Neuropsychological testing contributes functional information about cognitive abilities affected after injury, particularly memory and attention. These results complement symptom reports and clinical assessment by examining performance more directly. Repeated or monitored findings can help characterize the course of dysfunction and support research into recovery, although the overview does not specify particular tests or scoring systems.
Symptoms can provide an ongoing measure of neurological recovery, including changes in headache, dizziness, memory difficulty, and attention. Monitoring helps researchers and clinicians observe whether effects improve or remain persistent over time. It also supports investigation of factors that influence recovery, especially when combined with clinical assessment, neuropsychological testing, and imaging information.
Neuroscience research is evaluating advanced imaging and potential biomarkers to improve understanding and detection of mTBI-related dysfunction. These approaches may complement clinical findings by examining brain changes not visible on routine imaging. Their broader purpose is to support better characterization of injury, clarify recovery patterns, and guide strategies aimed at preventing persistent cognitive, emotional, and physical effects.
