Introduction: Sleep quality is often thought to be a key determinant of cognitive performance, particularly in older adults who experience age-related changes in sleep architecture. However, the extent to which nightly variations in sleep quality impact next-day cognitive performance remains unclear-in part because it has only recently become practical to ...

Sleep plays a role in memory consolidation, with slow oscillations (SO) and sleep spindles (SP) in non-rapid eye movement sleep being central to this process. While closed-loop auditory stimulation of slow oscillations has been well studied, precise real-time targeting of individual sleep spindles to assess their memory impact has remained technically cha ...

Closed-loop auditory stimulation (CLAS) is a brain modulation technique in which sounds are timed to enhance or disrupt endogenous neurophysiological events. CLAS of slow oscillation up-states in sleep is becoming a popular tool to study and enhance sleep's functions, as it increases slow oscillations, evokes sleep spindles and enhances memory consoli ...
