Changes in Task‐evoked Pupil Dilation during Emotional Memory as a Marker of Noradrenergic Function in Healthy Aging and MCI

Abstract

Background: Improved memory for negative events is supported by the locus coeruleus‐noradrenergic (LC‐NA) system. As the LC is one of the first structures exhibiting tau pathologies in AD, in vivo markers for structural and functional changes in the LC are required.
