title: Acetylcholinesterase-containing nerve fibers in the dura mater of guinea pig, mouse, and rat.
abstract: The cholinergic innervation of the dura mater in the guinea pig, mouse and rat has been investigated. The dura mater is provided with a cholinergic innervation. After short incubation times (4--6 hours) we found acetylcholinesterase (AChE)-containing nerve fibers in close relationship with the main meningeal blood vessels. After longer incubation times, AChE-containing nerve fibers appear also in the meningeal tissue proper. Chemical sympathectomy, performed with the neurotoxin 6-hydroxy-dopamine, does not seem to interfere with the pattern of the dural cholinergic innervation. The findings are discussed.
