In vivo Locus Coeruleus activity while awake is associated with REM sleep quality in healthy older individuals

Ekaterina Koshmanova, Alexandre Berger, Elise Beckers, Islay Campbell, Nasrin Mortazavi, Roya Sharifpour, Ilenia Paparella, Fermin Balda, Christian Berthomier, Christian Degueldre, Éric Salmon, Laurent Lamalle, Christine Bastin, Maxime Van Egroo, Christophe L. M. Phillips, , Gilles Vandewalle

This study finds that higher locus coeruleus activity during wakefulness in older adults is linked to worse sleep quality and reduced theta band power during REM sleep.
