Structure of neurons and neurogliocytes of associated departments of mesoaccumbocingular dopaminergic system in rats

The purpose of the paper was morphometric analysis of neurons and neurogliocytes in mesoaccumbocingular dopaminergic centers to select the associated departments supplying the normal function of dopamine mediation. The mesoaccumbocingular dopaminergic system is submitted by nucleuses of the midbrain, sending the dopaminergic fibers into the nucleus accumbens, which function is associated with research (addictive) behavior, and into the anterior cingular cortex, determining emotions of self-sensation. On the basis of the proper data devoting to volumetric reconstruction of the brain structures and a number of morphometric parameters of neurons and neurogliocytes from this system, the parts of the centers are selected which, according to opinion of the authors, have the leading role in the functioning of dopaminergic system. These structures are: the medial part of the paranigral nucleus of the ventral tegmental area and the medial territory of the compact part of the substance nigra in the anterior department of the midbrain, the medial part in the middle of n. accumbens and the III layer of the supragenual part of the anterior cingular cortex (Cg2) located in the same plane, the VI layer of the pregenual part of the anterior cingular cortex (Cg3) at the level of the basis of the forward nipper.
