Established that one of the factors promoting development of the psycho-nervous diseases, are various kinds of social deprivation. The purpose of this study was investigation of importance of social interactions at the early period of postnatal in development of resistance of the nervous system against the psychogenic stress in the adult rats. At weaning,(More)
The problem of adequate animal model of depression still remains. In our experiments depression-like condition on white rats were reached by the chronic stressors of psychogenic nature. Stress was carried out in a modified shuttle chamber of active avoidance. At the very beginning of the study (the first stage of stress) an animal was forced to develop a(More)
Behavior and short-term memory function were studied in adult rats risen under conditions of partial intraspecies social deprivation. Testing of delayed responses (and emotional state) showed that the partial deprivation of intraspecies communication at the early stage of postnatal ontogeny led not only to disorders of short-term memory in the adult rats,(More)
An individual's zoosocial experience plays a significant role in the formation of adaptive behavior in animals. Published data show that significant restriction of intraspecies interactions induces impairments of higher nervous activity, including such functions as learning, memory, and the control of emotions. These changes are particularly marked when(More)
A new model of depression based on use of stressors of the psychogenic nature has been created. It turned out that laboratory rats in a special stress-camera were unable to elaborate bilateral reaction of active avoidance, which later on led to formation of their depression-like state. Development of such their state was confirmed by analysis of tests(More)
