Development of an effective brain-machine-interface (BMI) system for restoration and rehabilitation of bipedal locomotion requires accurate decoding of user's intent. Here we present a novel experimental protocol and data collection technique for simultaneous non-invasive acquisition of neural activity, muscle activity, and whole-body kinematics during various locomotion tasks and conditions.

Establishing a Focal Demyelination Mouse Model via a Two-Point Injection of Lysophosphatidylcholine
0 Views •
2025
This video demonstrates the generation of a focal demyelination mouse model using a two-point Lysophosphatidylcholine (LPC) injection. The skull of an anesthetized mouse is exposed. The injection coordinates are determined, and a hole is drilled to enable LPC injections at targeted sites. LPC induces focal demyelination of neurons via inflammation, while a two-point injection ensures its sustainability.

Modeling Neonatal Intraventricular Hemorrhage Through Intraventricular Injection of Hemoglobin
0 Views •
2025
This video demonstrates a method to generate a rat model of neonatal intraventricular hemorrhage. In this procedure, an anesthetized rat pup is injected with hemoglobin into the lateral ventricle of the brain. The hemoglobin causes oxidative stress and releases heme, simulating intraventricular hemorrhage. The resulting damage to brain tissues, driven by reactive oxygen species and inflammatory cytokines, leads to ventricular enlargement, a common consequence of intraventricular hemorrhage.

The autologous blood injection model of intracerebral hemorrhage in mice described in this protocol uses the double injection technique to minimize risk of blood reflux up the needle track, no anticoagulants in the pumping system, and eliminates all dead space and expandable tubing in the system.
FAQs
Depth determines where the therapeutic agent is deposited and therefore how closely delivery matches the treatment goal. An intradermal placement targets the skin, a subcutaneous placement reaches tissue beneath the skin, and delivery near deeper tissues may be appropriate for selected procedures. Choosing the correct layer helps improve local precision and limits unnecessary exposure to surrounding areas.
Anatomical landmarks help the clinician identify the intended treatment area and guide needle placement consistently. This planning supports accurate delivery into the selected tissue layer rather than adjacent structures. Landmark-based guidance is especially relevant when the goal is localized anesthesia or treatment of a specific scalp disorder, because imprecise placement can reduce treatment precision and increase tissue injury risk.
A scalp injection concentrates an agent at a selected treatment site, which can limit exposure to the rest of the body compared with approaches that distribute medication more broadly. This local strategy may be useful when the clinical goal is confined to the scalp. It does not eliminate procedural risks, so patient assessment, appropriate dosing, and careful technique remain necessary.
The procedure begins with patient assessment, selection of the treatment site, and sterile preparation. The clinician then uses anatomical landmarks to guide a needle through the skin and deposits the chosen agent at the intended depth. The specific layer, dose, and injection pattern depend on the treatment goal, while careful handling helps reduce pain, bleeding, infection, and tissue injury.
The treatment objective, the agent being delivered, and the selected scalp tissue layer all influence the approach. Local anesthesia, corticosteroid treatment, and injection-based approaches for certain hair-loss conditions may require different placement decisions. Clinicians also consider patient-specific findings during assessment. Matching dose and depth to the indication supports treatment precision and may reduce avoidable complications.
Medical applications include providing local anesthesia for procedures, delivering corticosteroids for inflammatory scalp disorders, and supporting injection-based treatment approaches for certain hair-loss conditions. The expected outcome depends on the indication, agent, dose, and placement accuracy. Across these uses, sterile preparation and monitoring for pain, bleeding, infection, or tissue injury are important parts of responsible care.
