Schematic of the LAN intervention procedure.
To reduce the first-night effect, we have applied an additional nocturnal NPSG session on the first night (Night 0) before performing the main study on the second and third nights (Nights 1 and 2). After Nights 1 and 2, participants underwent fMRI while performing n-back tasks (0-, 1-, and 2-back tasks). Abbreviations: LAN, light at night; NPSG, nocturnal polysomnography; fMRI, functional magnetic resonance imaging.
