The present study shows the effectiveness of using polyunsaturated fatty acids in pregnant rats in order to prevent behavioral alterations in neonatal rats caused by the action of the pathogenic peptide factors of blood serum with perinatal damage of the central nervous system.
An analysis was made of the dynamics of probabilistic characteristics of the rat behaviour in the process of extinction of orienting-investigating behaviour in the "open field". Estimation of the entropy value related to behaviour permitted to divide the rats into two groups. The rats with high entropy values differed from those with low values by a more(More)
By means of ethograms record and analysis, connection has been studied between the properties of rats behaviour organization in the open field, determining the level of behaviour entropy in this test, and the speed of conditioned reflexes formation in the Skinner chamber. According to behaviour entropy level the rats are significantly divided into four(More)
Psychogenic trauma inflicted to mothers (Wistar rats) during pregnancy is more tragic for establishment of psychoemotional functions in offspring than in the rat pups whose mothers survived prior to pregnancy the stress connected with threat of life. The “antenatal stress” causes in the one-month-old offspring the depression-like behavior, while the stress(More)
Breach of locomotor functions and spatially oriented behaviour of rats' cubs after intraamniotic administration of the blood serum of children was shown to depend on the ontogenetic maturity and motor disturbances of donors. Injections were carried out on 14-th day of rats pregnancy.

In Wistar's rats, the postnatal influence of maternal behaviour on the motor and emotional state and the anxiety level of the posterity born from the intact rat-mothers-ambidexter but reared by the intact mothers-ambidexter with the motor deficit, were investigated. From the first day of life, the rat-mothers with the removed part of the sense-motor cortex(More)
