MicroRNAs play crucial roles in the brain and are potential targets for modeling neuro-degeneration. However, perturbing miRNA levels is challenging due to the short length of miRNA and inaccessibility of the brain tissue. This video presents a method for antagomir design and brain specific delivery using a neuropeptide in mice.

MicroRNAs have significant roles in brain structure and function. Here we describe a method to enforce hippocampal miRNA over-expression using stereotactic injection of an engineered miRNA-expressing lentivirus. This approach can serve as a relatively rapid way to assess the in vivo effects of over-expressed miRNAs in specific brain regions.
FAQs
Three-dimensional coordinates translate an anatomical target into a planned location, while the stereotactic apparatus keeps the animal’s head stable during placement. Target depth adds a vertical dimension, helping the needle or cannula reach the intended region rather than merely its surface. Together, these controls support localized delivery and make later molecular, cellular, or behavioral effects easier to associate with that brain site.
An anatomical atlas or imaging provides the spatial reference for selecting a brain target and estimating the appropriate path. After the head is stabilized, that reference helps align the needle or cannula with the chosen location and depth. This alignment is important because the method is intended to confine delivery to a defined region, supporting more interpretable links between the intervention and neural effects.
The substance determines the primary experimental outcome. Drugs can support localized manipulation, tracers can label neural structures, viral vectors can target neuronal populations, and cells can be introduced into a selected site. Because these materials serve different purposes, the same spatial delivery strategy can investigate circuit organization, alter brain function, or examine cellular responses within a defined region.
Localized delivery helps distinguish effects arising from one brain region from changes produced elsewhere. This spatial control allows investigators to connect a molecular or cellular change with neural-circuit activity and, when measured, behavior. The approach therefore strengthens interpretation of cause-and-effect relationships in neuroscience, particularly when studying brain function or mechanisms associated with disease.
The workflow begins by selecting a brain region and determining its three-dimensional coordinates with an anatomical atlas or imaging. The animal’s head is then stabilized in a stereotactic apparatus, and a fine needle or cannula is guided to the planned location and depth. A controlled infusion deposits the chosen substance at that target for subsequent analysis.
Core equipment includes a stereotactic apparatus for head stabilization and a fine needle or cannula for delivery. Researchers also rely on an anatomical atlas or imaging to guide target selection, along with the substance being studied, such as a drug, tracer, viral vector, or cells. Controlled infusion is the key delivery condition that limits deposition to the selected site.
Stereotactic Brain Injection can support localized manipulation, labeling, and monitoring of neuronal populations. Investigators can then relate these site-specific interventions to molecular or cellular changes and to behavior. Such results help connect brain regions with neural-circuit function, clarify disease mechanisms, and inform research into potential therapeutic strategies.
