  • EEG Activity during Realization of Manual Movements by Individuals with
           Different Characteristics of the Alpha Rhythm
    • Authors: A. G. Morenko
      Abstract: We examined 105 19- to 21-year-old men with a high or low individual modal alpha-frequency in their background EEGs. Latencies of the sensorimotor simple and complex (choice) reactions, rate capabilities of the nervous processes in the tapping test, and spectral power and coherence of the frequency EEG components were estimated. Estimations were obtained for each examined person in the resting state and during finger movements with a force loading (bending of the fingers in the fist and their spreading). Men with relatively high background modal frequencies of the alpha rhythm were characterized by a higher level of the attention selectivity and more local modifications of EEG activity related to realization of manual movements. Somewhat less-differentiated patterns of cortical activation were typical of persons with lower modal alpha-frequencies; this may correlate with a lower plasticity of the cerebral processes under conditions of the control of manual motor activity with force loading and maintenance of the pre-set movement rate. Men with higher modal alpha-frequencies demonstrated better rate indices in the performance of sensorimotor reactions.

  • Effects of Camellia Sinensis Extract on Passive Avoidance Learning and
           Hippocampal Neurogenesis in Rats
    • Authors: P. Hasani; H. S. Tehrani; P. Yaghmaei; N. H. Roudbari
      Abstract: We investigated the effects of a concentrate of green tea (extract of Camellia sinensis) on passive avoidance learning and hippocampal neurogenesis in male Wistar rats. Twenty-one male rats were divided into control, sham, and experimental groups. Rats of the control group were left intact, sham rats received infusions of 1.0 ml of distilled water for 8 weeks, while experimental rats received 1.0 ml of brewed green tea with a concentration of 0.04 g/ml. After eight weeks and behavioral testing, brain samples were taken, and 6-μm-thick sections were prepared from the hippocampus and examined microscopically using hematoxylin+eosin staining. Results of the passive avoidance tests confirmed improved learning after green tea concentrate administration (P < 0.01). Treatment of the experimental group by the extract increased noticeably the density (number per test area) of neurons (intensity of neurogenesis) in the CA3 area and dentate gyrus of the hippocampus (P < 0.001).

  • Effects of Doxorubicin on Behavior of Rats and Distribution of NCAM in
           their Brain

      Abstract: It was found that considerable structure-dependent changes in the distribution of neuronal cell adhesion molecules (NCAM) are observed in the brain of rats under conditions of doxorubicin-induced cardiomyopathy. This is accompanied by decreases in the intensity of locomotor and orientational/ research activity of the animals and changes in the stress-related indices in the “Open field” test.

  • Peculiarities of Activation of the Upper Limb Muscles in Humans during
           Realization of Two-Joint Movements
    • Authors: T. A. Abramovich
      Abstract: Coordination of the activity of flexors and extensors of the shoulder and elbow joints during realization of slow cyclic two-joint movements by the upper limb of the tested subjects was examined; the above movements were performed within the horizontal plane. The subject tracked the trajectory of the command signal shown on a monitor. Test movements corresponded to circular shifts of a handle; there were initiated in either clockwise (Lcw) or counterclockwise (Lccw) directions. An external loading could be also applied in the above directions (Mcw and Mccw, respectively). Surface (integral) EEGs were recorded from eight muscles of the upper limb and shoulder belt. As was found, the EMG amplitudes at opposite directions of tracking the target trajectory were dissimilar. At the clockwise direction of the external loading, the EMG amplitudes of most examined muscles during the counterclockwise movement were higher than those shown during the clockwise movement. Parameters of EMGs depended on the mechanical parameters of the movement. Under Mccw conditions, shorter loading waves act upon flexors of both joints, while longer waves act upon extensors. The situation is opposite under Mcw conditions (longer waves influence the flexors, while shorter waves act on the extensors).

  • Expansion of Visual Receptive Fields in the Extrastriate Visual Cortex:
           Dependence on the Trajectory of a Moving Stimulus
    • Authors: D. K. Khachvankian; A. L. Ghazaryan; B. A. Harutiunian-Kozak; M. M. Momjian; H. R. Aslanian
      Abstract: Regularities of spatial expansion of receptive fields (RFs) of visually sensitive neurons upon application of moving visual images were investigated in the cat extrastriate visual cortex (area 21a). The RF size and their spatial infrastructure were first defined by presentation of stationary flashing stimuli, and horizontal and vertical axes (HA and VA, respectively) of classical RFs were determined. Then the lengths of the above axes were carefully measured by spatial scanning of the RFs with moving visual stimuli. It was found that dynamic expansion of the RF sizes was, as a rule, linked to the trajectory of a moving stimulus across the RF. Stimulus motion along the RF HA resulted in significant extension of this axis but not of the VA, while the its motion along the RF VA usually caused extension of only this axis, while another axis underwent negligible changes. These results demonstrate that spatial expansion of the RFs correlates mainly with the trajectory of stimulus motion across the RF. Such an effect probably results from excitation of the neuron under study by the influences coming from adjacent cortical neural networks. Thus, neural circuits localized outside the RF play a decisive role in modulation of the qualitative and quantitative characteristics of classical RFs, hence ensuring precise central processing of incoming visual information.

  • Effects of Blockers of Large-Conductance Cation Channels of the Nuclear
    • Authors: O. A. Kotyk; A. B. Kotlyarova; N. I. Pavlova; S. M. Marchenko
      Abstract: Currents through large-conductance cation channels (LCC channels) in the nuclear membrane of cerebellar Purkinje neurons and hippocampal pyramidal neurons of the CA1 area were recorded using the patch-clamp technique. Later on, LCC channels were also found in the nuclear membrane of cardiomyocytes and other cells. In our study, we tried to find blockers of LCC channels, which is important for determining the physiological functions of these channels. It was found that a few N-cholinoblockers, in particular dithylinum and atracurium, are capable of blocking the above channels. Agonists of N-cholinoreceptors (acetylcholine and carbacholine) do not affect the activity of these channels.

  • Dynamics of the H Reflex and Tonic Activity in the Human m.Soleus at a
           Voluntary Movement of the Upper Limb
    • Authors: E. I. Slivko; G. A. Bogutskaya
      Abstract: In tests on healthy volunteers, we examined the effects of voluntary flexion of the elbow joint on the magnitude of the H reflex recorded from the ipsilateral m. soleus and on tonic EMG activity of this muscle. The H reflex was subjected to two-phase modulation; a period of facilitation lasting up to 300 msec was replaced by subsequent long-lasting inhibition. Tonic EMG-activity of the m. soleus induced by moderate voluntary contraction of its antagonist did not undergo significant changes under these conditions. As is supposed, changes in the intensity of background presynaptic inhibition exerted on afferents of the H reflex arc are the reason for the observed shifts in the magnitude of this reflex.

  • Structural/Functional Characteristics of Organotypic Spinal Cord Slices
           under Conditions of Long-Lasting Culturing
    • Authors: O. A. Rybachuk; Yu. A. Lazarenko; V. V. Krotov; N. V. Voitenko
      Abstract: Organotypic cultures of the spinal cord possess significant advantages, as compared with routine cell systems in vitro; the cytoarchitectonics, cytospecificity of the cells, cell-to-cell connections, and other characteristics of spinal cord tissues are preserved to a considerable extent. We analyzed structural/functional characteristics of organotypic spinal cord slices of mice under conditions of long-lasting (one to three weeks) culturing. Immunohistochemical staining and patch-clamp recordings from cells of the substantia gelatinosa showed that the morphology of different cell types and cell-to-cell connections typical of normal spinal nerve tissue are clearly manifested in such organotypic spinal cord cultures. This is why that such a technique of spinal cord culturing can be successfully used in subsequent experimental studies, in particular, in the examination of different-type damages of the spinal cord.

  • Effects of a Nociceptin Receptor Antagonist on Experimentally Induced
           Scratching Behavior in Mice
    • Authors: K. Duvan Aydemir; O. Gunduz; A. Ulugol
      Abstract: Itch and pain are two distressing sensations sharing a lot in common. In addition to the periphery, the central nervous system is proposed as a therapeutic target for the development of antipruritic drugs. The contribution of the most recently discovered opioid peptide, nociceptin/orphanin FQ (N/OFQ) and its receptor (NOP) in pain transmission is controversial. It seems to be pronociceptive when given supraspinally, but elicits an antinociceptive action when injected spinally. Here, we examined whether the N/OFQ system plays a role in experimentally induced pruritus. Scratching behavior was produced by intradermal administration of serotonin (50 μg/50 μl/mouse) or nociceptin (30 nmol/50 μl/mouse) to Balb/c mice. JTC-801 (1, 3 or 10 mg/kg, i.p.), a NOP receptor antagonist, attenuated both serotonin- and nociceptin-induced scratches. When given intradermally, JTC-801 (100 nmol) significantly reduced serotonin-induced but not nociceptin-induced scratches. We propose that antagonizing NOP receptors either systemically or localy may be a novel approach in the development of antipruritic agents.

  • Reactions of Microglial Cells in the Sensorimotor Cortex of Rats after
           Transient Ischemia
    • Authors: L. M. Yaremenko; O. M. Grabovyi
      Abstract: Blood supply disturbances in the cortex after carotid ligation or microembolization of the vessels of the hemisphere by adipocytes result in an increase in the number of Iba-1+ microgliocytes in the hemisphere; the intensity of such increase depends on the degree of ischemic damage. The reaction of microglia to this damage shows a systemic character, since it is also manifested in cortical parts that did not directly undergo destructive (necrotic) changes and were beyond the zones of ischemization. An immunomodulator, Immunofan, increased the number of Iba-1+ microgliocytes within the acute period after transitory ischemia; within the recovery period, their number significantly decreased. This coincided with the more favorable time course of the postischemic process as a whole. The latter phenomenon can be considered a manifestation of the neuroprotective properties of Immunofan.

  • Effects of Cadmium on the Activity of Matrix Metalloproteinases and
           Metallothionein Level in the Rat Brain
    • Authors: O. Fomenko; H. Shiyntum; O. Shaulska; A. Shevtsova; G. Ushakova
      Abstract: We studied the effects of long-lasting treating with cadmium in two different doses (0.1 and 1.0 μg/kg) on the activity of matrix metalloproteinases (MMP2 and MMP9) and metallothionein level in the rat brain. Cadmium in a higher dose (1 μg/kg) caused a decrease in MMP2 activity but increased that of proMMP9 in the brain. The level of MT in the hippocampus and cerebellum dropped with both Cd doses. Thus, even small Cd doses exert specific effects on the MMP activity and MT level in the brain.

  • Anxiolytic Properties of Derivatives of
           1-Methoxycarbonylmethyl-3-Arylamino-7-Bromo-5-Phenyl-1,2-Dihydro-3 H
    • Authors: S. A. Andronati; T. L. Karaseva; A. V. Zamkovaya
      Abstract: TSPO receptors are peripheral benzodiazepine receptors (PBDRs). Unlike central benzodiazepine receptors (CBDRs), PBDRs (TSPO receptors) are widely presented in organs and tissues of animals and humans; these receptors are involved significantly in the regulation of many physiological processes in the norm and pathologies. Elucidation of the molecular bases of interactions between the TSPO receptors and their ligands is an important task of modern pharmacochemistry. We studied the anxiolytic properties of some derivatives of 1-methoxycarbonylmethyl-3-arylamino-7-bromo-5-phenyl-1, 2-dihydro-3H-1,4-benzodiazepin-2-one (compounds 1-7), which demonstrate considerable affinity for TSPO and CBDRs. The anxiolytic activity was estimated in experiments on rats in the “Conflict situation” test, while the intensity of motor activity was estimated in the standard “Open field” test. All tested compounds demonstrated a rather high selectivity in binding with TSPO receptors; compounds 1–4 manifested significant anxiolytic properties. Compound 2 demonstrated the maximum anxiolytic activity; after binding with TSPO receptors, Ki(TSPO) = 19, while Ki(CBDRs) > 10000 nM. All studied compounds were characterized by low toxicity; their LD50 exceeded 500 mg/kg.

  • Modulation of Synaptic Reactions of the “Nociceptive” Neurons in the
           Cat Cortex upon Stimulation of the Periaqueductal Gray and Application of
           Some Pharmacological Agents
    • Authors: T. Sh. Labakhua; T. K. Janashia; G. I. Genevanishvili
      Abstract: We examined the effects of electrical stimulation of the periaqueductal gray (PAG) and systemic morphine injections on postsynaptic processes in neurons of the cat somatosensory cortex, which were activated by nociceptive influences. Stimulation of the PAG resulted in long-lasting suppression of synaptic reactions induced by stimulation of dental pulp nociceptors. There was certain parallelism within the conditioning effects of PAG stimulation and effects of systemic introduction of morphine. Ionophoretic application of strychnine on such pyramidal cortical neurons did not evoke paroxysmal depolarization shifts (PDSh) of the membrane potential in such neurons. At the same time, surface application of this agent on the cortex (which influenced extensive populations of cortical neurons) resulted in the development of considerable PDShs. This observation confirms the synaptic nature of the above shifts. Applications of strychnine using both techniques resulted in the blockade of, first of all, early IPSP components in pyramidal neurons but did not affect significantly late components of these potentials; this is indicative of different geneses of the above components. It is supposed that the early IPSP component is generated due to activation of axo-somatic inhibitory synapses, while the late component of such reactions is related to activation of inhibitory synapses localized in the dendrites. The mechanisms of modulation of postsynaptic reactions of somatosensory cortex neurons developing upon activation of high-threshold (nociceptive) afferent inputs are discussed. Such modulation is probably based on changes in both pre- and post-synaptic intracortical cell structures.

  • Effects of the α-Adrenergic, Kisspeptinergic, and Melatonin Systems on
           the Morphofunctional State of Cells of the Adrenal Cortex in Mature Rats
    • Authors: A. S. Bezlyudna; A. S. Pustovalov; M. G. Matvienko; N. E. Dzerzhinskii
      Abstract: In experiments on young mature (three-month-old) albino rats, we examined the effects of the α-adrenergic, kisspeptinergic, and melatonin systems on the morphofunctional state of the adrenal cortex. Manifestations of the effects of these regulatory factors in the three zones of the adrenal cortex were dissimilar. For the glomerular zone, the state of the α-adrenergic system and high levels of melatonin played a crucial role, while the role of the kisspeptinergic system was secondary. Kisspeptinergic regulation played a major role in the modulation of the state of cells in the fascicular zone. Simultaneously, spongyocytes of this zone were inactivated upon blocking of both the kisspeptinergic and α-adrenergic systems. Adequate levels of the activity of the α-adrenergic and kisperpinergic systems were simultaneously necessary to maintain the sufficient state of spongyocytes in the reticular zone of the adrenal cortex, while effects of melatonin were not decisively important.

  • Contrast-Dependent Restructuring of Neuronal Visual Receptive Fields in
           the Cat Extrastriate Cortex
    • Authors: B. A. Harutiunian-Kozak; A. L. Ghazaryan; M. M. Momjian; D. K. Khachvankian; H. R. Aslanian
      Abstract: Spatial modifications of neuronal visual receptive fields (RFs) in the cat extrastriate cortex were studied. The response properties and spatial organization of the RFs of area 21a neurons were investigated using visual stimuli of two opposite contrasts, with particular attention to the stationary structure of these RFs. It was found that the infrastructure of the RF of a visually sensitive neuron undergoes certain restructuring related to the contrast of the visual stimuli used. In most cases, discharge centers of the RF subfields changed their response profile and spatial localization within the RF depending on the stimulus contrast. Stationary RFs defined by presentation of flashing spots of two opposite contrasts (bright and dark) differed from each other quantitatively and qualitatively, indicating the influence of background illumination on the pattern of neuronal responses. It is hypothesized that the RF surrounding significantly influences central processing of incoming visual information and image recognition in the extrastriate cortex.

  • Effects of Stereotactic Introduction of Baclofen in the Medullary
           Cardiovascular Nuclei of Rats
    • Authors: L. M. Shapoval; O. V. Dmytrenko; A. M. Naumenko; T. L. Davydovska; V. F. Sagach
      Abstract: In rats anesthetized with urethane (1.7 g/kg, i. p.), we investigated the effects of stereotaxic microinjections of baclofen into the medullary nuclei involved in the neural control of cardiovascular activity (nuclei paramedianus, ambiguus, and reticularis lateralis). Changes in the hemodynamic parameters (systolic and diastolic blood pressure and heart rate) were measured. Injections of the above GABAB receptor agonist (10–7, 10–6, or 10–5 M, 0.1 μl) into the medullary cardiovascular nuclei was accompanied by changes in the blood pressure, the magnitude and direction of which depended not only on the baclofen concentration but also on the site of injection (into one nucleus or another). Injections of the agent into the nucl. ambiguus at a 10–7 M concentration resulted in an increase in the blood pressure, but a 10–5 M concentration provided significant reduction of the systolic and diastolic blood pressure. If baclofen was injected into the nucl. reticularis lat., the blood pressure also increased or decreased but the concentration dependence was opposite to the above described. Injections of the agent into the nucl. paramedianus were always accompanied by significant increases in the blood pressure. Changes in the heart rate following baclofen injections into the nuclei under study were insignificant. The specificities of the baclofen-induced effects are probably related to peculiarities of the functioning of GABAB receptors, the activation of which may mediate the effects of multiple neuronal mechanisms.
