Meningeal Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes. [@artifacts2022]
Meningeal neurons innervate the meninges (dura, arachnoid, pia mater) and are involved in headache mechanisms and meningeal inflammation. [@proteomic2021]
