[The effect of neurotization after a long period following its termination on the behavior of rats differing by nervous system excitability].

Behaviour of two strains of rats with high and low levels of excitability of the nervous system was studied in 6 months after the end of neurotization and compared with that of the intact (control) rats. Stable disturbances were revealed in behavioural components which were initially characteristic for each strain of rats. In rats with the high threshold of nervous excitability the emotional component of behaviour was disturbed and in those with the low threshold the motor disorders were observed.
