title: [Neurovasal relations in the human neocortex].
abstract: Different types of interneurons producing nitric oxide in human brain motor cortex were studied by means of histochemical reaction to NADPH diaphorase--the marker of nitric oxide synthase. Non-synaptic dendrito-, axo- and somatovasal contacts between typical smooth and spinous checking interneurons were shown. A hypothetic scheme of local blood circulation control is represented, after which these cells, exerting inhibitory synaptic action on pyramidal neuron at the same time cause vasodilatation by secreting nitric oxide near to the capillary.
