Histochemical fluorescent study was made on regeneration of the aminergic nerves of rat cerebral arteries after uni- or bilateral superior cervical ganglionectomy.
Regeneration started mainly from the proximal portion of the internal carotid artery between 4 and 6 weeks and reached the maximum in number between 9 and 12 months after sympathectomy.
The number of maximally regenerated nerves was about half of that in normal rats.
Regenerated aminergic nerves were generally unbeaded and the intensity of fluorescence was weak.
