title: [Morpho-functional and hodological peculiarities of ascending dopaminergic system of Rhodeus sericeus (Cyprinidae)].
abstract: Using the methods of tyrosine hydroxylase (TH) immunohistochemistry combined with nerve fiber labeling with carbocyanin dye DiI (1,1',dioctadecyl-3,3;3',3'-tetramethylindocarbocyanine perchlorate), the distribution of catecholaminergic (CE) neurons and their ascending projections to the basal telencephalon were studied in adult Amur cypriniform fish Rhodeus sericeus. Highly specialized complex of CE neurons was demonstrated in diencephalon. Six populations of TH-immunopositive neurons were detected in the area of posterior tuberculum, two of them were double-labeled, indicating the presence of dopaminergic projections to the ventral portion of the telencephalon (striatum). In the posteriotuberal area, two populations of CE cells were identified (small round neurons and large pear-shaped cells) which probably could correspond to the populations of sensomotor and limbic cells in mammals.
