[Morphological studies of the regulatory mechanisms of intracerebral blood circulation].

The intracerebral branches of the posterior and medial cerebral arteries in the area of the grey and white substances of the parietal, occipital and temporal cerebral lobes, of the nuclei in the superior and inferior colliculi in the tectum mesencephali. as well as in the pons have been studied in 36 male corpses at the age of 5--49 years by means of Cajal, Koelle, Furness and Costa methods. Presence of sensitive neural terminals, cholinergic plexuses has been stated in the intracerebral artery walls with the diameter up to 100 mcm and more, as well as adrenergic neural network on the arteries with the diameter up to 100 mcm and more, as well as adrenergic neural network on the arteries with the diameter up to 40 mcm and more. Besides, near the cerebral substance vessels monoaminocytes situating both in the area of the sphincter torus and in the arterial walls have been revealed. A suggestion is made that the proper neural and other apparatuses of the intracerebral circulatory bed play a certain role in regulation of the local cerebral circulation.
