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)
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)
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)
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)
This review is devoted to neuroanatomical and neurophysiological mechanisms of Pavlovian fear conditioning with a focus on the amydgalae, two subcortical nuclear groups, as primary structures responsible for controlling conditioned fear responses, and synaptic plasticity at their afferent and efferent projections as a cellular mechanism to mediate the(More)
A comparative morphometric analysis of MRI brain tomograms of term ant preterm born children was conducted. Common morphometric indexes and a novel quantitative parameter, a coefficient of corpus callosum (kCC), developed with regard to prenatal cortex ontogenesis pattern were applied to the study in order to get objective structural characteristics of the(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)
Inhibitory interneurons in the cortex are regarded as an important intracortical module-forming factor. We report here our studies of the expression of three calcium-binding proteins in interneurons in the sensorimotor cortex of the cat. Calbindin-expressing non-pyramidal neurons were found to be distributed non-uniformly in layer III, forming large groups.(More)
