[The effect of isolation from the mother in the neonatal period on general development, brain formation and behavior].
24-hr isolation of newborn rats from mother decreases their body weight and growth of the brain mass. The fiber cerebral structures are delayed in their development in deprived newborn rats. Thyroid gland also becomes altered resulting in its hypofunction. The data obtained suggest that the neonatal isolation is a strong stress delaying rather considerably development of a number of cerebral structures, leading to endocrinal disfunction and altering the behaviour.
