The video demonstrates intracerebral injection of Zika virus suspension in an adult mouse to induce neurodegeneration. An anesthetized mouse is secured in a stereotaxic frame, and a hole is drilled into the exposed skull for injection. A suspension of the Zika virus is injected into the brain tissue. The viral infection causes inflammation, leading to neurodegeneration.

Drosophila is widely used as a model system to study neurodegeneration. This protocol describes a method by which degeneration, as determined by vacuole formation in the brain, can be quantified. It also minimizes effects due to the experimental procedure by processing and sectioning control and experimental flies as one sample.

Generating a Mouse Model with a Spinal Cord Injury

Source: Kumar, S., et. al. Mouse Model of Pressure Ulcers After Spinal Cord Injury. J. Vis. Exp. (2019)This video demonstrates a detailed induction of spinal cord injury in mice. The anesthetized mouse is dissected to expose T9-T10 vertebrae, and their spinous processes are removed. The exposed spinal cord is then transected to inflict the injury. The surgical area is then closed, and the mouse is allowed to recover.
FAQs
They allow researchers to examine related changes at multiple levels, including axonal degeneration, motor neuron death, glial activation, and impaired neuroinflammation or repair. Comparing these features within an experimental system can help connect molecular and cellular abnormalities with spinal circuit dysfunction and resulting motor deficits, rather than treating neuronal loss as an isolated event.
These processes represent distinct but related features of spinal disease. Axonal degeneration reflects damage to neuronal projections, motor neuron loss captures degeneration of cells essential for movement, and glial activation indicates responses from supporting nervous-system cells. Examining them together helps determine which changes accompany disease progression and which may be relevant to treatment development.
Cultured neurons, organoids, genetically modified organisms, and injury-based paradigms reproduce different aspects of spinal disease. Simpler systems can support focused study of cellular mechanisms, whereas more complex models can capture broader interactions involving circuits, glia, and motor function. No single approach represents every feature, so interpretation depends on the biological question being asked.
Selection should match the model to the feature under investigation and the intended experimental outcome. Researchers may consider whether they need to study axonal degeneration, motor neuron death, glial activation, impaired neuroinflammation or repair, motor deficits, biomarkers, or treatment responses. Because each system captures different aspects of human spinal disease, model choice affects how findings are interpreted.
A study generally begins by choosing an experimental system that reproduces the relevant disease feature, followed by examination of cellular, molecular, or circuit changes. Researchers can then relate those findings to motor deficits, identify candidate biomarkers, and evaluate potential interventions. The workflow may use cultured neurons, organoids, genetically modified organisms, or injury-based paradigms, depending on the question.
Once a model reproduces a relevant disease process, it can provide a platform for testing interventions intended to reduce neuronal damage or improve spinal function. Drug treatments, gene therapies, and regenerative strategies can be examined in relation to changes such as motor neuron loss, axonal degeneration, glial activation, or impaired repair, helping assess their potential effects in a defined system.
These systems connect measurable cellular and molecular changes with functional outcomes. Researchers can examine disease-associated features alongside motor deficits to identify signals that may serve as biomarkers of degeneration or dysfunction. This relationship is particularly important in neuroscience because it links observations in spinal tissue and cells with changes in motor performance relevant to disease progression.
