A new study sheds light on the neurobiology of cravings for certain foods women experience while pregnant. According to researchers, during pregnancy, the brain undergoes alterations to functional connections in the reward systems, as well as taste and sensorimotor centers. Pregnant females become more sensitive to sweet foods and develop binge eating behaviors toward high-calorie foods. Pregnancy induces a full reorganization of the mesolimbic neural circuits via D2R dopaminergic neurons in the nucleus accumbens.
