Odor as a contextual cue in memory reactivation in young infants

► Infants trained to move a mobile by kicking in the presence of coconut or cherry odor. ► Infants forget what they learned 1 week later. ► One-week forgetting alleviated if infants exposed to the moving mobile and training odor 24 h prior. ► Forgetting not alleviated if exposed to the moving mobile and a novel odor or with no odor present. ► Memory reactivation context dependent.
