Mother-pup interactions during a short olfactory deprivation period in young rats.

abstract：:The prenatal development of cyclic motility (CM) in the human is disrupted by maternal diabetes, but appears normal by the end of gestation. To determine whether birth and adaptation to postnatal life reveal new or persisting abnormalities in CM, 24 newborn infants of insulin-dependent diabetic mothers (IDMs) and 24 n...
