Cortical regions recruited for complex active-learning strategies and action planning exhibit rapid reactivation during memory retrieval

► Memory performance was superior following active study versus passive study. ► This active-learning benefit was pronounced for spatial location memory. ► ERP correlates of spatial retrieval differed for active versus passive study. ► Reactivation of the brain regions involved in study occurred during retrieval. ► This reactivation reflected higher-order operations involved in active study.
