A review of neurobiological factors underlying the selective enhancement of memory at encoding, consolidation, and retrieval

Publication date: Available online 2 May 2019Source: Progress in NeurobiologyAuthor(s): Rebecca Crowley, Daniel Bendor, Amir-Homayoun JavadiAbstractHow is the strength of a memory determined? This review discusses three main factors that contribute to memory enhancement - 1) emotion, 2) targeted memory reactivation, and 3) neural reinstatement. Whilst the mechanisms through which memories become enhanced vary, this review demonstrates that activation of the basolateral amygdala and hippocampal formation are crucial for facilitating encoding, consolidation, and retrieval. Here we suggest methodological factors to consider in future studies, and discuss several unanswered questions that should be pursued in order to clarify selective memory enhancement.
