We investigated the distribution of gamma aminobutyric acid, tyrosine hydroxylase and nitric oxide-producing elements in a cherry salmon Oncorhynchus masou brain at various stages postnatal ontogenesis by immunohistochemical staining histochemical staining. The periventricular region cells exhibited morphology neurons glia including radial glia-like contained several neurochemical substances. Heterogeneous populations hydroxylase-, acid-immunoreactive, as well nicotinamide adenine...

In the brain of teleost fish, radial glial cells are major type astroglial cells. To answer question as to how glia structures adapt continuous growth brain, which is characteristic salmonids, it necessary study various types (neuronal precursors, cells, and in a state neuronal differentiation) integrative centers salmon (telencephalon tectum opticum), using rainbow trout, Oncorhynchus mykiss, model. A distribution several molecular markers telencephalon with identification neural...

The distribution of proliferative zones, NO-producing cells and apoptosis areas in the medulla oblongata, cerebellum, optic tectum, thalamus hypothalamus Amur sturgeon Acipenser schrenckii was investigated, using techniques immunoperoxidase staining proliferating cell nuclear antigen (PCNA), neuronal nitric oxide synthase TU-NEL-labeling fragmented DNA. It has been established, that brain NO can act both as a cytotoxic proapoptogenic factor, which stimulates proliferation. presence elements...

The data of our investigations contribute to understanding cellular mechanisms the teleost fishes CNS forming in postembryonic development. revealed peculiarities structural and neurochemical organization description basic histogenetic processes (proliferation, migration neuronal cell differentiation) during brain fish, which have signs fetal organization, widen existing knowledge about histogenesis these structures It seems conceivable, that postembrional development some neurotransmitters...

Brain anatomy and structure, composition of the neurons, cytoarchitectural maps were compared between five species Acipenser, one Huso two Scaphirhynchus. Morphological differences in forebrain structure genera apparent. The evolutionary history Acipenseridae has been marked by an extensive mosaic radiation development inner their brains. Members Scaphirhynchus have a very simple telencephalon differing significantly from that Acipenser. It is clear neuromorphological variation sturgeon will...

Anatomy, cytoarchitecture and neuronal composition of the i everted-type telencephalon various sturgeon species; (Acipenser baeri Br., Acipenser stellatus Pall., nudiventris Lov., ruthenus L., gueldenstaedtii Huso huso L.) were studied by classical histological methods TV-imaging. Hemisphere was significantly variable across species genus, while neurone proved to be rather conservative. Neurones mainly undifferentiated, isodendritic type. The question homology structures between everted...

Objective – the study of age-related changes in neural groups cerebral cortex and cerebellar process upward ontogenesis. Material methods . The work was done on post-mortal material (75 left hemispheres, 62 cerebellum) obtained from children birth to 12 years old who died as a result injuries without damage brain. Using computer morphometry Nissl stained frontal histological sections taken layer III fields 8, 6o р 37ac, well granular paramedian lobule (H VII B), area group section total...

BACKGROUND: Human posterior associative cortex, including its temporoparietal–occipital subarea, is important in cognitive control, verbal activity, sensory stimuli processing, and attention regulation, visuomotor responses, situational decision making. Despite data suggesting the prolonged formation of these higher mental functions during postnatal ontogeny, cortex has been insufficiently characterized with respect to microstructural transformations individual functionally specialized zones...

Objective – the study of age-related changes in thickness cortex and its layers posterior lobe cerebellum children. Material methods. The work is performed on postmortem material (62 cerebellum), obtained from children aged birth to 12 years who died as a result injuries without brain damage. Using computer morphometry painted method Nissle frontal histological sections cortex, taken region right left quadrangular lobules (H VI) top folia cerebellum, was measured cortical molecular granular...
