title: The "richness" of sympathetic innervation. A comparison of cerebral and extracerebral blood vessels.
abstract: The number of adrengeric nerves was quantified, on both cerebral and femoral blood vessels. No difference was found between the two vascular beds. The data failed to establish a "richer" innervation of cerebral vessels. This is in agreement with my previous, extensive, subjective, and unpublished impression. Consequently, the suggestion of others, which ascribes certain features of cerebrovascular behavior to an unusually rich vascular innervation, remained unproved.
