The influence of stresses of different origin and their combined effect on the psychoemotional status of rats

The work shows the specificity of the influence of stresses of different origin (psychogenic trauma and forced swimming), as well as their combined effects on the psychoemotional status and eating behavior of male rats in the early period after exposure. Mental trauma caused by vital stress led to the development of anhedonia, suppression of eating behavior in combination with a decrease in exploratory activity and an increase in emotional tension in animals in the Open Field and Elevated Plus Maze tests. Stress caused by forced swimming led to depression of motor and exploratory activity. The combination of stresses of different origin led to cross-adaptation with leveling of depression caused by vital stress, as well as normalization of exploratory and motor activity, suppressed as a result of forced swimming.
