The interaction (synchronization) of activity of the medial prefrontal cortex, hippocampus and basolateral amygdala have been studied in the course of performance of conditioned avoidance reflex. The pre-stimulus expectation period was characterized by low-frequency delta-activity (1-4 Hz) with the source (according to criteria of Granger causality) in the(More)
The influence of spatial imprinting on cognitive activity of adult mice F1 from DBA/2J C57BL/6J in a transformable multialternative maze has been studied. A control mice initially learned in a maze with "direct" and "bypass" pathway between feeders. They successfully formed a food-getting habit after 9-10 sessions using mainly direct pathway, so the final(More)
The interaction between the medial prefrontal cortex, the ventral hippocampus, and the basolateral amygdala was studied during execution of a conditioned avoidance reflex. Slow δ activity at 1–4 Hz was recorded during the prestimulus period, with a source meeting the “Granger causality” criterion located in the prefrontal cortex, along with a θ rhythm at(More)
The damage of dorsal hippocampus in mice F1 from DBA/2J and C57BL/6J on the learning in conditions of free choice in a complex multialternative maze was studied. It was revealed that the HPC-mice were able to form a 4-links food-getting habit in the cyclic form. The main differences affected the conjugation of the investigate activity, behavioral efficiency(More)
We studied the effects of food deprivation, spatial complexity of environment, and cognitive strain on blood level of testosterone in male (C57Bl/6×DBA/2)F1 mice. Hormone concentration decreased after exposure to any factor and this decrease depended on combined impact to the factors. Testosterone concentration was most sensitive to cognitive strain against(More)
We report here studies of spatial imprinting on the formation of a cyclical food-procuring skill in a multiple-choice maze in adult DBA/2J C57BL/6J F1 mice in conditions of free choice. In contrast to control mice initially trained in conditions of environmental constancy, the experimental group was exposed to changes in the maze space over the 3 min of 1–2(More)
We report here studies of the consequences of lesioning of the dorsal hippocampus of DBA/C57 F1 mice during training in a complex multiple-choice maze in conditions of free selection. Hippocampectomized (HPC) mice were found to be able to form a four-component food-procuring skill in cyclic form. The main features were linked with the nature of the(More)
