Antenatal glucocorticoids routinely used to accelerate fetal lung maturation in human pregnancy at risk of preterm delivery decrease synaptic density and complex electrocortical activity in the fetal sheep brain at 0.87 gestation. We examined whether the effects of betamethasone on synaptic density depend on maturation of hypothalamo-pituitary-adrenal (HPA) axis and whether these effects are reversible...
Knowledge of morphofunctional effects on the fetal brain induced by exogenous glucocorticoids is limited. Recently, we reported alterations of both the neuronal cytoskeleton and electrocortical function in the ovine fetal brain after antenatal betamethasone treatment in doses used in perinatal medicine. In the present study we examined whether these changes are accompanied by morphological alterations...
