Abstract

The innervation of the middle cerebral artery (MCA) of the cat was studied by applying horseradish peroxidase (HRP) to the wall of the right MCA. After a survival period of 48 to 72 hours, the bilateral superior cervical ganglia, middle cervical ganglia, stellate ganglia, T-4 sympathetic paravertebral ganglia, geniculate ganglia, semilunar ganglia, nodose ganglia, and brain stem including midbrain, pons, and medulla oblongata were removed to be processed with tetramethyl benzidine. HRP-labeled neurons were found in the ipsilateral superior cervical ganglion, semilunar ganglion, and dorsal raphe nucleus. The other areas did not have HRP activity. The results suggest that the adrenergic nerves innervating the MCA originate in the ipsilateral superior cervical ganglion, the sensory nerve originate in the ipsilateral semilunar ganglion, and the serotonergic nerves originate in the ipsilateral dorsal raphe nucleus. Cerebral arterial constriction may relate to the intrinsic (intracerebral) neurogenic pathway involving the trigeminal nerve and the dorsal raphe nucleus.
