This video demonstrates a method to trace the origins of sensory neurons in the dura mater using fluorescence microscopy. A retrograde tracer is introduced into the exposed dura mater of an anesthetized rat. The tracer is taken up by sensory neuronal axons and travels retrogradely to their cell bodies...

This video and protocol demonstrate how to implant a glass-covered cranial window in rodents. These preparations can be used for chronic in vivo two-photon imaging of the neocortex over time scales of months. It may also be used for other types of imaging, including optical intrinsic signal imaging.

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 protocol presents a method for creating a large unilateral craniotomy over the temporal and parietal regions of the mouse cerebral cortex. This is especially useful for real time imaging over an expansive area of a cortical hemisphere.
FAQs
Control depends on creating the opening with microsurgical instruments while preserving nearby neural structures and cerebrospinal fluid pathways. The incision must provide sufficient access to the underlying tissue without unnecessarily disturbing the cortex, spinal cord, or blood vessels. This balance is important because the procedure must support the intended intervention while limiting tissue injury during access.
Watertight closure restores the dura mater’s protective barrier after the surgical opening has served its purpose. It also helps reduce cerebrospinal fluid leakage, which is a central concern when fluid pathways have been exposed. In practice, closure is therefore not merely the final step; it contributes to protection of neural tissues and supports recovery after intracranial or spinal intervention.
The cortex, spinal cord, blood vessels, and cerebrospinal fluid pathways all require careful protection. Their proximity to the operative opening means that access must be created with precision rather than broad disruption. This attention to surrounding anatomy helps limit tissue injury and preserves the neural and fluid-containing structures needed for normal protection and function.
The procedure follows a focused sequence: surgeons create a controlled dural opening with microsurgical instruments, use that access to reach the underlying neural tissue, and then close the dura watertight. Throughout the process, they protect the cortex or spinal cord, blood vessels, and cerebrospinal fluid pathways. The sequence links surgical access directly with restoration of protection.
A Durotomy Procedure can provide access for several types of intracranial and spinal intervention. Supported uses include tumor removal, vascular lesion repair, and decompression, with the specific application depending on the condition being treated. In each case, the opening functions as a route to the target tissue while careful execution seeks to limit injury and postoperative complications.
In neuroscience, opening the dura can provide access to underlying neural tissues for experimental procedures as well as clinical interventions. Its relevance comes from combining access with protection: microsurgical handling limits disruption, while watertight closure helps restore the surrounding barrier afterward. This makes the procedure useful when investigators or surgeons need controlled access to intracranial or spinal structures.
