Compound muscle action potential recording quantitatively assesses functional diaphragm innervation by phrenic motor neurons. Whole-mount diaphragm immunohistochemistry assesses morphological innervation at individual neuromuscular junctions. The goal of this protocol is to demonstrate how these two powerful methodologies can be used in various rodent models of spinal cord disease.

Organ specific sensory neurons are difficult to identify. Fast Blue tracing is used to identify nodose neurons innervating the airways for cell sorting. Sorted nodose neurons are used to extract high quality ribonucleic acid (RNA) for sequencing. Using this protocol, gene expression of airway specific neurons is determined.

Endothelial corneal transplantation is a surgical technique for treatment of posterior corneal diseases. Mechanical microkeratome dissection to prepare tissue results in thinner, more symmetric grafts with less endothelial cell loss and improved outcomes. Dissections can be performed at the eye bank prior to corneal transplantation surgery.
FAQs
Different stimulus classes are handled through sensory nerve endings that detect mechanical, thermal, and chemical changes at the corneal surface. Their activation initiates neural signaling to blink and tear-production reflexes, linking local environmental detection with rapid protection and maintenance of the ocular surface during exposure.
The subbasal plexuses form a branching neural layer supplied by fibers that enter through the limbus. This arrangement places sensory axons close to the corneal surface, helping explain how nerve architecture relates to corneal sensitivity and pain. It also provides a structural feature for studying nerve disruption and regeneration after injury or surgery.
After injury or surgery, examining corneal innervation helps researchers relate nerve disruption and regeneration to changes in pain, sensitivity, and wound healing. The same framework connects structural recovery with the functional consequences of altered corneal sensory input, allowing neural changes to be studied alongside surface homeostasis over time.
Imaging and functional assessments can characterize corneal nerve architecture and its function, then relate findings to pain, sensitivity, wound healing, or regeneration. In neuroscience, these measures also provide noninvasive indicators of peripheral neuropathy and other neurodegenerative conditions. This makes the cornea a useful window for studying neural health.
Because sensory axons supplying the cornea arise primarily from the ophthalmic branch of the trigeminal nerve, corneal findings can be interpreted within a broader sensory-neural context. Studying their architecture and function therefore links ocular protection and surface biology with questions about peripheral nerve health in neuroscience.
A useful evaluation considers both nerve appearance and associated sensory consequences. Changes in nerve pattern or function can be interpreted in relation to pain, sensitivity, wound healing, and regeneration, rather than as isolated anatomical findings. This combined perspective is especially valuable after injury or surgery and when corneal measures are used to study neuropathy.
