The effects of lesioning of the dorsal hippocampus on the psychoemotional state of Wistar rats were studied. Hippocampal lesions did not affect the learning process, but affected mainly the pattern of psychoemotional manifestations in all animals regardless of the typology of higher nervous activity. All animals showed reductions in the extremes of types of(More)
Analysis of psychoemotional behavioral component in Albino and Wistar rats during solving a cognitive task showed that intra-population differences were determined by the relationship between passive and active forms of unconditioned reactions. Quick-learning rats from both populations were characterized by the dominance of active forms of psychoemotional(More)
The study aimed at revealing psycho-emotional manifestations of Wistar rats in a problem situation when they had to solve a food-getting task in a multi-alternative maze. Bilateral lesion of dorsal hippocampus did not affect the learning process while the pattern of psycho-emotional manifestations changed in all the animals irrespective of their individual(More)
Studies of the effects of 10-min clinical death in mongrel rats, induced by complete circulatory arrest, on the mechanisms of memory, showed that the content of already formed memories ("what to do?"), i.e., the structure of a food-procuring habit, motivational activity, and the level of organization of behavior, was completely retained 12 days after(More)
Retention of memory traces was tested on the 12th day after 10-min clinical death (CD) produced by the total cessation of blood circulation in Albino rats previously trained for operant food conditioning in a multiple alternative maze. It was found that the structure of memory trace (sequence of operant actions in the maze), motivation activity and habit(More)
