Moderate alcohol exposure during the rat equivalent to the third trimester of human pregnancy alters dopamine regulation of GABAA receptor-mediated transmission in the basolateral amygdala

Fetal ethanol (EtOH) exposure leads to a range of neurobehavioral alterations, including deficits in emotional processing.The basolateral amygdala (BLA) plays a critical role in modulating emotional processing, in part, via dopamine (DA) regulation of GABA transmission.This BLA modulatory system is acquired during the first two weeks of postnatal l
