Abstract

Objectives: Under longstanding segregation the rats demonstrate changes in behavioral responses, birth rate, weight gain, levels of Alpha tocopherol in blood, number of eosinophils and lipid per oxidation that show developing stress conditions. Methods: Statistical processing was assisted by software package Statistica 6.0; absolute values were compared applying Student’s t-test. Findings: It is a well-known fact that the emotional status of an organism is predetermined by the limbic structures of the brain. The study presents the data on the microelectrode investigation of neuronal activity under normal conditions and under stress in the limbic system of the outbred rats that were put under the conditions of the prolonged sexual conflict situation. The multidirectional changes have been observed in hypothalamus impulse activity, in septum, in hippocampus and in amygdale of the brain. Applications/Improvements: The study puts forward the assumption that hypothalamus and amygdale nuclei complex are the most labile in the limbic system under conditions of developing emotional stress.
