Neurochemical events underlying the activity of the dopamine synapse during the retrieval of memory and its impairment ("psychogenic" amnesia) are considered in the paper. Physico-chemical parameters of operation of D2 receptor and catechole content were investigated in various brain areas (striatum, neostriatum, hypothalamus, amygdala, frontal cortex,(More)
postoperative period a transpedicular fixing of its elements is often used. Usually the transpedicular systems are formed of rods which as a result form a design of the frame type, fastening by screws to vertebras. Such design should be rigid and perceive loadings operating from the spine without essential deformations. From the perfection point of view of(More)
The development of submissive behaviour in C57BL/6J mice in the sensory contact model was associated with an increase in the content of serotonin (5-HT) in the amygdala, hippocampus, dopaminergic nuclei A11, A10, A9, as well as in the caudate nucleus and hypothalamus after 10 and 20 days of confrontations compared to the controls. The level of 5-HT(More)
In addition to its common activating action, the DA system is involved in the functional specialization of the brain areas which participate in the expression of discrete behavioral components. The evidence for different levels of activity of the mesocortical DA system in aggressive and submissive mice were obtained. In C57BL/6J mice, confrontations(More)
The work discusses the neurochemical correlates of rat brain dopamin-synaptic activity after injection of 0.5 mg/kg rudotel (medazepam) as compared with intact animals. The parameters of functioning of D2-receptors in [3H]-dopamine binding, the content of catecholamines and their metabolites (high-performance liquid chromatography with electrochemical(More)
Tyramine (TA) revealed earlier during the functioning of dopamine (DA)-receptors of the rat brain (after learning) in vivo was produced from dopamine bound by DA-receptors of the synaptic membranes in the system which was exposed to the influence of the microdischarge electroradialysis in vitro. It is shown that the formation of p-TA under these conditions(More)
