Innervation of blood vessels in subcortical regions of the brain by immunoreactive neurons

Abstract

Human dorsal thalamic nuclei (VA, VL and Md), striatum,pallidum and capsula interna were studied. Structural elementsof neurons that provide afferent and efferent innervation ofblood vessels in the human brain were stained for NADPhdiaphorase,parvalbumin and calretinin. Such approachrevealing immunoreactive neurons with their branches made itpossible to identify two types of neurons: long-axonal and shortaxonal.Dendrite-vascular and axon- vascular contacts of theseimmunoreactive neurons were shown.
