[Reactions of pial microvascular effectors in regulating adequate cortical blood supply to neuronally isolated cerebral cortex].
Responses of pial arteries were studied in experiments on adult rabbits with the use of serial photomicrography of the cerebral surface under conditions of the enhanced activity of the brain cortex, induced by application of 0.5% strychinine. No significant differences in the responses of smaller and larger pial arteries as well in those of the sphincters at their off-shots and precortical arteries were found after dissection of all neural pathways of the vascular responses are neurogenic, the feed-back should operate locally, inside the appropriate cortical areas.
