In this research, we performed targeted memory reactivation (TMR) locally in one side of the brain to improved memories stored in a single hemisphere: Participants learned to associate words with left or right visual field locations while contextual odor was present. Presenting this odor again to a single nostril during post-learning naps selectively promoted memory for specific words stored in the related hemisphere (ipsilateral to the cued nostril) and modulates local sleep oscillations and coupling.
