Some neurons also respond to thermal stimuli, in either the warming or cooling direction. Stimulation of the middle meningeal artery leads to Fos expression in the trigeminocervical nucleus: The dura-muscular, dura-ligamentous connections in the upper cervical spine and occipital areas may provide anatomic and physiologic answers to the cause of the cervicogenic headache.

A rupture of a bridging vein causes a subdural hematoma. Subarachnoid hemorrhage in the rat substantially reduced the SP-immunoreactive nerve fibers of the dura mater, but left the CGRP-immunoreactive innervation unchanged. This study also observed a colocalization of NPY and norepinephrine in some nerve hte.

From this point of view, it has to innrvation assumed that the different terminals have different transducer properties despite their rather uniform ultrastructural appearance.

Neurons could also be activated by dural application of a number of algesic agents, including potassium chloride, capsaicin, buffer solutions of low or high osmolarity, or a mixture of inflammatory mediators bradykinin, PGE2, serotonin, histamine.
