Neuromodulation by the locus coeruleus (LC) plays a crucial role in cognitive processes related to learning, as well as memory consolidation (DOI: 10.1038/s41583-020-0360-9). Less is known about its role in memory retrieval. In this study, we explored this aspect following training of adult rats over a period of multiple days in an 8-arm radial maze to achieve robust spatial working memory (WM) and reference memory (RM) of the task. We then examined the consequence of patterned electrophysiological activation of the LC on the retrieval of recent (24h after the conclusion of training) or remote
