title: [Histochemical studies of the microvascular effectors regulating blood supply to the cerebral cortex].
abstract: The innervation of the pial arteries as well as the activity of enzymes (phosphorylase I, II, III, succindehydrogenase, lactate dehydrogenase, ATPase, GTPase and CTPase) responsible for vascular smooth muscle function were studied histochemically on total microscopic preparations of rabbit pia matter. An especially rich adrenergic and cholinergic innervation was found around the active microvascular effectors - sphincters of pial and precortical arterial off-shoots. The nerve fibers followed the radial arteries entering the cerebral cortex. No differences were detected between the pial arteries and active microvascular effectors in the enzyme activity.
