A comparative morphometric study was performed with MRI brain scans of term- and preterm-born infants. The structural characteristics of the brain were analyzed using conventional morphometric indices, and a novel quantitative parameter, the corpus callosum coefficient (kCC), was introduced based on patterns of the prenatal cortex ontogeny. All these(More)
Histochemical method of cytochrome oxidase demonstration was used to study its distribution in frontal sections of tectum of the midbrain in cat in normal conditions and after unilateral enucleation. Basic layers of this formation were demonstrated in normal conditions similar to those revealed using classical histological methods. After unilateral(More)
Cortical projections of the medial geniculate body have been studied in dolphin Phocaena phocaena by the method of anterograde degeneration of Fink--Heimer. For this purpose, in two animals a unilateral electrocoagulation of the thalamic auditory center has been performed. The caudal part of the microcellular nucleus of the medial-geniculate body has been(More)
Using histochemical determination of activity of the mitochondrial oxidative enzyme cytochrome oxidase (CO) in brain structures, metabolic activity both in turtles and in lizards has been shown to be higher in centers of the tectofugal channel (the tectal stratum griseum centrale, SGC; nucleus pretectalis ventralis, Ptv; thalamic nucleus rotundus, Rot;(More)
The age dynamics of corpus callosum development was studied on magnetic resonance images of the brain in children aged 2-11 years without neurological abnormalities and with infantile cerebral palsy. The areas of the total corpus callosum and its segments are compared in the midsagittal images. Analysis is carried out with the use of an original formula:(More)
Prenatal ontogenesis of temporal areas of the human cortex was studied. In the fetal cortex at the gestational age of 16-18 weeks three zones can be distinguished: marginal zone (eI layer), cortex plate and subplate. At 20-26 weeks cortex plate is divided into following layers: eII, eIII, eIV, eV and eVI, with "efferent" complex of layers being wider than(More)
Prenatal ontogeny of human neocortex have distinctive features that make it unique. Experimental data obtained on animal models could not be easily extrapolated on human corticogenesis of middle and late gestational period. Our research was aimed at features of human cortical pyramidal neurons development within 16-26 gestational weeks. Material was(More)
Despite a long history of research of cortical marginal zone (MZ) organization and development, a number of issues remain unresolved. One particular issue is the problem of Cajal-Retzius cells (C-R) identification. It is currently based on morphology and Reelin expression. The aim of this research is to investigate MZ cytoarchitectonics and Reelin-producing(More)
