The smells that newborn mice are exposed to (or “imprint” on to use the academic term) affect many social behaviors later in life, but how this happens is still a mystery. Scientists from Japan have now discovered the molecules necessary for imprinting. Their new study sheds light on the decision-making process and neurodevelopmental disorders such as autism spectrum disorders. It also proposes more effective use of oxytocin therapy for such disorders at an early age.
