  • Title: [Response of active microvascular segments in the pial artery system to photostimulation of the ey in the rabbit].
    Author: Baramidze DG, Gordeladze ZT, Levkovich IuI.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1986 Feb; 72(2):193-7. PubMed ID: 3699184.
    Abstract:
    Photomicrography revealed the dynamics of pial ertarial responses, their active segments in particular: the sphincters at offshoots of minor arteries from the larger vessels, and the precortical arteries. On retinal photostimulation, the precortical arteries were found to dilate quite often (72%); the sphincters at offshoots in 50%, and the minor arteries in 38% of cases, while the larger pial arteries showed no dilatation at all. The dilatation was most pronounced in the precortical arteries and in the sphincter areas (25% of the control diameter), and less significant in minor pial arteries (10%). The data obtained indicate that the precortical arteries are the basic vascular effectors of regulation of adequate microcirculation in the cerebral cortex.
