[Emotional intelligence and oscillatory responses on the emotional facial expressions].

Emotional intelligence-related differences in oscillatory responses to emotional facial expressions were investigated in 48 subjects (26 men and 22 women) in age 18-30 years. Participants were instructed to evaluate emotional expression (angry, happy and neutral) of each presented face on an analog scale ranging from -100 (very hostile) to + 100 (very friendly). High emotional intelligence (EI) participants were found to be more sensitive to the emotional content of the stimuli.

[EEG correlates of aggression and anxiety in a social interaction model].

Aggressiveness- and anxiety-related behavioral and oscillatory patterns were investigated in 49 18-30 year old subjects during virtual social interactions. The subjects were presented with pictures of "angry", "happy", and "neutral" faces and had to choose one out of three options: "attack", "avoid", or "make friends". Sources of cortical EEG were localized with sLORETA software.

[Reciprocal relationships between oscillatory systems of the brain].

Resting EEG data were collected from a sample of 146 children aged from 7 to 17 years and 132 adults aged from 18 to 32 years. Eysenck's, Spilberger's, Gray-Wilson's, and Goodman's questionnaires were used to assess personality and psychopathology. Using factor analysis, the covariance between spectral power measures was decomposed into factors reflecting common positive covariance and reciprocal relationships among different frequency bands.

[Structural changes in the tissues of white rats after capsaicin administration].

Tissue structure of albino rat lung, skin and cornea changing after administration of capsaicin (neurotoxin isolated from red pepper) was studied using light and electron microscope. 5 mg/kg dose causes tissue swelling and microcirculatory bed reaction. 200 mg/kg dose leads to more significant dystrophic tissue alterations.

[Reaction of cells of subcutaneous connective tissue to the activation and blockade of the peptidergic system].

Changes in the quantitative composition of subcutaneous connective tissue cells were examined after activation and blockade of the peripheral peptidergic system with capsaicin. The activating dose (5 mg/kg) of the agent was found to increase the quantity of mast cells in the subcutaneous connective tissue. Its toxic dose (200 mg/kg) elevated the histiocytic and fibroblastic index while the number of mast cells reduced.

[The microcirculatory disorders in deafferentation of the eye].

Microcirculatory disorders occurring in the eye of rats in the early period after deafferentation were studied. The blood flow in the iridic vessels became slower and permeability of the eye vessels was disturbed in the first hours and minutes after retrobulbar injection of the anesthetic trimecaine. Similar changes were encountered in division of the trigeminal nerve branches and in electrocoagulation of the sensory nucleus of the trigeminal nerve as well as in venous congestion induced by applying a ligature to the veins of the eyeball.

[Mechanism of the development of neuroparalytic keratitis].

There is a hypothesis that for appearance of the neuroparalytic keratitis a decisive role has cessation of discharge of trophic factors, demonstrating a polypeptide nature. from sensitive nervous endings. In order to check the hypothesis, deafferentation of the eye has been performed by means of electrocoagulation of the trigeminal sensitive nucleus in the medulla oblongata.

[Development of neuroparalytic keratitis after retrobulbar administration of trimecaine].

The blood flow in the iris vessels slowed down and the vessel permeability increased early after a retrobulbar injection of trimecaine, a local anesthetic, this resulting in the development of tissue edema. Two days later neuroparalytic keratitis developed. The authors suppose that early vascular disorders resultant from blocking of the sensitive nerves are among the causes responsible for later changes in the corneal trophics.

[Effect of deafferentation of the liver on hepatocytes located in various parts of the hepatic lobule].

Taking into account the data on functional heterogeneity of hepatocytes, situating in various parts of the hepatic lobule, influence of deafferentation of the cat liver on changes in the size of hepatocytes and their nuclei, as well as contents of glycogen and nucleic acids in their cytoplasm have been investigated. The greatest decrease of the glycogen contents and the greatest increase of the nucleic acids and the nuclei volume take place in hepatocytes, situating around the central vein.

[Effect of seduxen on conditioned reflex behavior and reactivity of the noradrenergic system of the rat brain].

It has been shown in experiments on white rats that administration of diazepam in a dose of 5 mg/kg reduces the emotional stress and activation of noradrenergic terminals during reproduction of conditioned avoidance responses. The role of the central noradrenergic system in the emotional stress control is discussed.

[Emotional-defensive behavior and noradrenergic forebrain structures].

Conditioned avoidance responses in rats increase the noradrenaline expenditure in forebrain. The animals which reproduce no conditioned response after learning as well as the animals with ECS-induced retrograde amnesia preserve the noradrenergic terminals reaction as well as the emotional component of the conditioned response. The extinction of the emotional component by repeated testing or diazepam administration decreases the noradrenergic terminals activation.

[Use of disulfiram in a histochemical study of the influence of different stimuli on the concentration of noradrenaline in brain structures].

With the help of the histochemical fluorescence method the changes in noradrenaline fluorescence of nuc. septi lateralis, nuc. interstitialis striae terminalis and nuc.

[Quantitative assessment of catecholamine fluorescence detected by the Falck method].

While using Falck's method, a number of simple and handy additional ways were suggested to carry on quantitative estimation of the fluorescence change of noradrenergic and dopaminergic terminals in a number of nuclei of the central nervous system. A device was used, which allows to obtain samples of brain of a given size and in a definite plane. The method we used makes it possible to treat simultaneously a great number of material at all the stages of work.

[An analysis of participation of central noradrenergic structures in the process of memory trace reproduction].

Variations of the noradrenaline content in noradrenergic terminals of different nuclei of the limbic system and the anterior hypothalamus were studied by the limuniscent histochemical method in the course of reproduction of a series of conditioned reflex reacitions in male Wistar rats. Both in reproduction of a conditioned passive avoiding responce and in training with inevitable conditioned reinforcement, a decrease of the noradrenaline content was found as compared with the control level. A lesser decrease was observed both in the animals that had been trained but did not reproduce the relfex reaction, and in the trained animals after repeated testing for 4 days following the training.

[Analysis of the participation of rat brain noradrenergic terminals in elaboration of conditioned passive avoidance response].

A change in a noradrenaline concentration in the noradrenergic terminals was investigated by the fluorescent histochemical method in pars ventralis nuc. interstitialis striae terminalis, nuc. septi lateralis and in nuc.
