Sleep spindle maturity promotes slow oscillation-spindle coupling across child and adolescent development [PDF]
eLife, 2023 The synchronization of canonical fast sleep spindle activity (12.5–16 Hz, adult-like) precisely during the slow oscillation (0.5–1 Hz) up peak is considered an essential feature of adult non-rapid eye movement sleep. However, there is little knowledge on

Slow oscillation amplitudes and up-state lengths relate to memory improvement. [PDF]
PLoS ONE, 2013 There is growing evidence of the active involvement of sleep in memory consolidation. Besides hippocampal sharp wave-ripple complexes and sleep spindles, slow oscillations appear to play a key role in the process of sleep-associated memory consolidation.

Sound asleep: processing and retention of slow oscillation phase-targeted stimuli. [PDF]
PLoS ONE, 2014 The sleeping brain retains some residual information processing capacity. Although direct evidence is scarce, a substantial literature suggests the phase of slow oscillations during deep sleep to be an important determinant for stimulus processing. Here,

Spindle-slow oscillation coupling correlates with memory performance and connectivity changes in a hippocampal network after sleep. [PDF]
Hum Brain Mapp, 2022 After experiences are encoded, post-encoding reactivations during sleep have been proposed to mediate long-term memory consolidation. Spindle-slow oscillation coupling during NREM sleep is a candidate mechanism through which a hippocampal-cortical ...

Targeted memory reactivation during sleep influences social bias as a function of slow-oscillation phase and delta power. [PDF]
Psychophysiology, 2023 To understand how memories are reactivated and consolidated during sleep, experimenters have employed the unobtrusive re-presentation of memory cues from a variety of pre-sleep learning tasks.

Endogenous memory reactivation during sleep in humans is clocked by slow oscillation-spindle complexes. [PDF]
Nat Commun, 2021 Sleep is thought to support memory consolidation via reactivation of prior experiences, with particular electrophysiological sleep signatures (slow oscillations (SOs) and sleep spindles) gating the information flow between relevant brain areas.

Slow oscillation-spindle coupling predicts enhanced memory formation from childhood to adolescence. [PDF]
Elife, 2020 Precise temporal coordination of slow oscillations (SO) and sleep spindles is a fundamental mechanism of sleep-dependent memory consolidation. SO and spindle morphology changes considerably throughout development.

Slow-oscillation activity is reduced and high frequency activity is elevated in older adults with insomnia. [PDF]
J Clin Sleep Med, 2020 High-frequency electroencephalographic activity (> 16 Hz activity) is often elevated during nonrapid eye movement sleep among individuals with insomnia, in line with the hyperarousal theory of insomnia.
