This video demonstrates the induction of handling-induced seizures in a mouse infected with Theiler's Murine Encephalomyelitis Virus (TMEV). The infected mouse, which has hyperexcitable neurons, is exposed to external physical stimuli. This exposure causes stress, leading to abnormal electrical activity in the neurons, which results in seizures.

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.
FAQs
Traumatic injury can disrupt neural circuits and initiate inflammation, while also altering the balance of synaptic activity. Together, these changes may increase network excitability, making abnormal electrical discharges more likely as the brain undergoes post-injury remodeling. Studying these mechanisms helps researchers connect the initial tissue damage with later seizure development and identify biological processes that may be targeted therapeutically.
Seizures may emerge as part of a progression from acute injury to chronic neurological dysfunction rather than appearing as an isolated event. Monitoring over time allows researchers to examine when abnormal activity begins, how seizure patterns evolve, and whether network changes persist. This temporal information supports the search for biomarkers of progression and helps distinguish early injury effects from later post-traumatic epilepsy-related changes.
Electroencephalography records abnormal electrical activity, whereas behavioral scoring captures observable seizure manifestations. Using both measures gives researchers a broader assessment than either approach alone because electrical abnormalities and visible behaviors provide different information about seizure expression. Their combined use supports more reliable characterization of seizure onset, recurrence, and progression within the injured mouse brain.
Researchers create a standardized traumatic brain injury using an impact-based procedure or fluid-percussion procedure. The controlled injury provides a consistent experimental starting point for examining subsequent seizure-related changes. Afterward, animals are monitored with electroencephalography and behavioral scoring, allowing investigators to relate the induced injury to abnormal electrical activity and recurrent seizure outcomes.
This model is useful when investigators want to test preventive or therapeutic interventions in the context of traumatic brain injury. Because monitoring can capture seizure onset and progression, researchers can assess whether an intervention influences abnormal electrical activity, behavioral seizures, or the development of longer-term neurological dysfunction. The approach therefore connects treatment effects with both acute and chronic consequences of injury.
The model can help define when seizures begin, describe how they progress, and identify biomarkers associated with post-injury network changes. It also provides a framework for linking tissue damage with altered neural-circuit function and chronic neurological dysfunction. These outcomes support neuroscience research on disease mechanisms, seizure monitoring, and the evaluation of strategies intended to modify post-traumatic epilepsy-related processes.
