Serotonergic innervation of cat cerebral arteries.
5-HT and 5-HIAA were measured in cat cerebral arteries by HPLC. Removal of both superior cervical ganglia or simultaneous lesions of dorsal and central raphe nuclei significantly decreased 5-HT levels but not those of 5-HIAA. This suggests that cat cerebral blood vessels are innervated by serotonergic fibers of different origin.
