[Serotoninergic nerve fibers in the area of the substantia grisea and the ependyma of the cerebral aqueduct].
An electron microscopic study of the midbrain gravy with the help of degeneration caused by serotonin-like neurotoxin 5,7-dihydroxytryptamine has shown that serotonergic terminals are responsible for the innervation of dendrites, neuron bodies and ependyma cells of the cerebral aqueduct. The detection of light, dark with prevailing fine transparent or large granular synaptic vesicles as well as vacuole degeneration evidences of the existence of several sources of serotonergic innervation of the central gray substance. Continuous damage of perivascular astrocytes of the central gray by neurotoxin allows a suggestion to be made that they are also the object of serotonergic innervation. Immunomorphological data on the presence of serotoninergic neurons in the cerebral gray are confirmed.
