[Dynamics of rat behavior in conditions of psychogenic stress during alcoholic motivation].

The goal of the work was to study behavior of rats in conditions of psychogenic stress on the background of ethanol intake. Experiments were carried out on 12 mature while rats weighing 150-200g. Before the beginning of the experiments during one month rats with high and low ethanol intake have been identified.

[Dynamics of the summary electrical activity of the dorsal hippocampus during development of experimental informational behavioral pathology].

Dynamics of dorsal hippocampal EEG changes were traced in cats during the short-term memory loads under conditions of the time deficit between the separate delayed reactions. Shortening the intervals between the tests from 3-5 min to 15-20 s led to an expressed ECoG desynchronization accompanied by an initial increase and later blockade of the hippocampal theta-rhythm. Hippocampal theta-activity changes under conditions of the time deficit was a result of emotional stress.

[Effect of self-stimulation of the septum pellucidum on disrupted delayed reactions in cats].

The effect of self-stimulation of the septum on impaired delayed reactions was studied on cats in a state of neurotization. Reduction of intervals between tests from 3-5 min to 30-40 s produced a complex of motor and vegetative reactions testifying to augmentation of emotional stress. This was followed by disturbance of short-term memory of complex perception of the location of food.

[Effect of increasing loading of short-term image memory on cat behavior].

The dependence of the short-term image memory on time intervals between separate tests was studied in cats with the method of delayed reactions. Shortening of the interval from 3-5 min to 30-40 sec caused in all experimental animals a disturbance of delayed reactions to complex and visual perception of food's location; the time of approaching the food increased, emotional stress hightened, intensive scratching of the body, licking the hair and mewing appeared. The latter reactions are considered as a manifestation of the brain mechanisms of autoregulation aimed at prevention of neurosis development.
