[Age characteristics of the efferent innervation of the arteries of the human pia mater].
By means of histochemical reactions revealing acetylcholinesterase, cholinacetyl-transferase activity and using glyoxylic acid, formation and involution of cholinergic and adrenergic neural fibres have been studied in the pia mater arteries of the human brain (in the temporal, parietal and occipital areas) beginning from 12-14 weeks of the intrauterine development up to 86 years of age. The development and formation of the vascular neural apparatus goes in parallel with differentiation of the cerebral areas which they feed. Maturation of the cholinergic neural plexuses takes place earlier, and age involution--later than those of the adrenergic neural plexuses. In mature age, concentration of the neural fibres in the walls of the pia mater arteries having the same calibre but taken from different areas of the brain varies significantly.
