[Cholinergic and adrenergic innervation of human intracerebral arteries in ontogenesis]

The intracerebral branches of the anterior, medial and posterior cerebral arteries in the cerebral tissue sections or revealed by means of the preparation method have been studied in cortical parts of the acoustic, optic and motor analyzers at various age periods (from the second half of pregnancy up to 86 years of age). On the intracranial arteries of all the age groups, the adrenergic and cholinergic fibers are revealed in the radial arteries and their large branches. Differences in the maturation rate and in involution of neural conductors have been stated between the cholinergic (revealed by means of reactions for acetylcholinesterase) and adrenergic (reaction with glyoxylic acid) conductors.
