title: [The experience of maternity exerts a significant effect on the shaping of behavior in rat progeny in early postnatal ontogeny].
abstract: Maturation of specific behavioral reactions were studied in 13-24-day-old rats born by females with prior maternal experience (group A) and maternally naive females (group B). The rats of group B showed later eyes opening and earlier maturation of grooming and manipulation than the group A rats. The development of behavioral reactions was found to be related with eye opening in the rats of group A and maturation of manipulation in group B rats. The results suggest that the maternal influence is a significant environmental factor, which affects the early postnatal development of rat pups.
