Here we present a protocol to visualize spatial correlation of calcitonin gene-related peptide (CGRP)-immunoreactive nerve fibers and blood vessels in the cranial dura mater using immunofluorescence and fluorescent histochemistry with CGRP and phalloidin, respectively. In addition, the origin of these nerve fibers was retrograde traced with a fluorescent neural tracer.

This video demonstrates the procedure for establishing a subarachnoid hemorrhage rat model. An anesthetized rat is implanted with probes to measure intracranial pressure and cerebral blood flow. The target site is identified, and the needle is inserted at a pre-chiasmatic position. Autologous blood is then injected into the subarachnoid space, increasing intracranial pressure and decreasing cerebral blood flow, establishing the model.

FAQs
Placement in or immediately adjacent to the dura mater concentrates the experimental solution near tissues surrounding the brain and spinal cord. This localization allows researchers to examine responses associated with a defined meningeal site rather than relying only on effects produced throughout the nervous system. The approach is therefore useful for connecting local exposure with nearby sensory or inflammatory signaling.
The dura mater lies near sensory nerve fibers that can respond to local chemical, inflammatory, or pharmacological signals. Delivering a compound at this interface lets investigators evaluate whether those signals alter sensory activity or related nervous-system responses. This relationship is especially relevant when studying how meningeal events may contribute to pain signaling and headache mechanisms.
A local meningeal delivery places the experimental compound at or near the dura mater, whereas conventional systemic administration does not specifically target that interface. The localized approach can help researchers evaluate effects associated with meningeal tissues and nearby sensory fibers under more controlled exposure conditions. This distinction supports clearer investigation of local mechanisms and candidate treatment responses.
The technique can examine chemical, inflammatory, and pharmacological signals acting at the meningeal interface. Researchers may use these different signal types to study how nearby tissues and sensory nerve fibers influence nervous-system activity. Comparing responses to such signals can help clarify meningeal biology, neuroinflammation, pain signaling, and mechanisms associated with headache.
A study first selects an experimental solution and a meningeal target relevant to the research question. The solution is then delivered into or immediately adjacent to the dura mater, followed by assessment of responses in the nearby sensory or nervous-system tissues. This workflow provides a controlled way to relate local exposure to biological or pharmacological outcomes.
Researchers may choose Dura Mater Injection when they need to investigate processes occurring at the meningeal interface, including meningeal biology, headache mechanisms, neuroinflammation, or pain signaling. It is also useful for evaluating candidate treatments or tracing responses in tissues that are difficult to access through conventional systemic administration. The method connects a defined local exposure with neuroscience outcomes.
By placing a candidate compound near the dura mater, investigators can examine how local pharmacological signals affect nearby sensory nerve fibers and nervous-system activity. These observations may indicate whether a treatment influences meningeal or pain-related responses under controlled local conditions. The resulting data can support assessment of candidate treatments without limiting the investigation to systemic exposure alone.
