title: [The exploratory behavior in an open field and in a burrowing chamber of rats with different predispositions to stress].
abstract: The peculiarities of oriental research behavior and correlation between activities of catecholaminergic and serotoninergic brain systems dependently on their stress resistance degree were investigated in Wistar rats. The experiments showed that resistant (R) to a sound stimulus rats differed from nonresistant (NR) ones by increased research activity under moderate stress in the open field test and by decreased research behavior level in the cell chamber test. The biochemical analysis of biogenic amines in different brain structures revealed increased norepinephrine levels in stress R rats, and increased dopamine and serotonin levels in NR ones. The findings suggest that inborn behavior regulation in animals with different stress resistance is determined by different correlations between serotonin-dopamine and norepinephrine brain systems activities.
