The purpose of this review is to analyze research possibilities and limitations of several methods, technical tools and their combinations for elucidation of absence epilepsy mechanisms, particularly the childhood absences. Despite the notable collection of simultaneous recording of clinical electroencephalography (EEG) and behavioral changes in relation to(More)
80 It is well known that the background extracellular concentration of dopamine in the brain is below 0.1 μ M and only transiently increases to values of 1 μ M after activation of dopaminergic neurons [1]. The high-affinity Na-dependent dopamine transporter (DAT) and norepinephrine transporter (NET) are involved in the maintenance of the extracellular level(More)
The problem of development of lateralization of motor systems in the course of early ontogenesis is important for understanding regularities of formation of functional characteristics of motor control. To solve these tasks, in the 8–74-day old rat pups the presence of lateralization was studied in two motor tests: the choice of the preferable rotation(More)
The mechanisms that underlie the early loss of the male reproductive function are still unknown. Therefore, investigation of this problem is an important task. The medial preoptic nucleus takes part in the regulation of sexual behavior; however, the role of glycine transmission in this nucleus has not yet been studied. Our study focuses on these questions.
The influence of early manipulatory skill training on forepaw preference in adult state of rats was investigated. One group of Wistar rats was trained at the age of 21-28 days of life, another one at the age of 30-37 days of life. Second test of both groups was performed at the age of 120-127 days of life. It was found that after training at the age of 21(More)
To study functional characteristics of the brain cortex motor areas in developing white rats and to determine their interlocation in rat pups at the different age and at critical terms of formation of motor representations in the process of postnatal development, mapping of neocortex frontal areas at the age up to 1.5 months was performed using(More)
Study of peculiarities of formation of preference in use of one of forepaws at learning of the manipulatory food-procuring skill has been carried out at different stages of early ontogenesis of white rats. It was established that as early as at the 3-week age the rat pups were already able to learn getting food from a narrow test-tube; however, no expressed(More)
The problem of motor lateralization in ontogenesis is important for understanding adaptation development. In our experiment adolescent (P28-P30) and adult (P120) rats were trained in an eight-arm radial maze and their motor behaviour compared during training. During learning, the adult rats typically started by moving either left or right direction in the(More)
