Research of the prenatal origins of laterality is equivocal with some studies suggesting that fetuses exhibit lateralized behavior and other not finding such laterality.

This longitudinal study investigated whether fetuses from 24 to 36 weeks of gestation showed increasing lateralized behaviors during mouth opening and whether lateralized mouth movements are related to fetal age, gender and maternal self-reported prenatal stress.ParticipantsFollowing ethical approval, fifteen healthy fetuses (8 girls) of primagravid mothers were scanned four times from 24 to 36-gestation.
