[Dynamics of somatic development and formation of behavioral acts in Wistar rat pups under conditions of repeated maternal separations in pre-weaning period].

[Article in Russian]


Comparative analysis of the dynamics of somatic and sensorimotor development was performed in Wistar rat pups subjected to short (30 min) and long (180 min) daily maternal separations in the first 10 days after birth. Somatic and sensorimotor development in the pre-weaning period in rat pups subjected to the long maternal separations was shown to be considerably slower than in those subjected to the short removals from the nest. The most significant delay in the formation of sensorimotor reactions occurred in the second half of pre-weaning period. The results suggest that pup's rearing conditions during the first ten postnatal days are important for the timely development of functions of the nervous systems.
