referenceMalerba et al. (2022) analyzed the space-time profiles of sleep spindles and their coordination with slow oscillations on the electrode manifold.

claimGlobal slow oscillations (SOs) are characterized by traveling wave profiles moving anteriorly to posteriorly, larger amplitudes at frontal electrodes, and higher modulation of spindle amplitude by SO phase.

referenceMalerba et al. (2018/2019) investigated the spatio-temporal structure of sleep slow oscillations on the electrode manifold and their relationship to spindles.

claimRecent research has attempted to determine the spatio-temporal profiles and organization of sleep slow oscillations (SOs) and spindles in young adults.

claimOlder adults exhibit a decreased count and density of K-complexes and spindles, as well as reduced slow oscillation (SO) amplitude compared to young adults.

claimThe time-locking of spindles to the phase of slow oscillations (SOs) promotes memory in adults, while disrupting this SO-spindle phase coupling using optogenetics impairs memory in mice.

claimMalerba et al. (2019) identified three clusters of slow oscillations (SOs): Global, Local, and Frontal SOs, which differ in amplitude, spatio-temporal profile, and their relationship to spindles.

claimGlobal slow oscillations (SOs) orchestrate long-range neural communication, quantified via directed information flow, which correlates with overnight memory improvement.

referenceNiknazar et al. (2022) proposed that slow oscillations promote long-range effective communication, serving as a key mechanism for memory consolidation in a broken-down network.

claimThe rate of coupling of spindles to slow oscillations (SOs, 0.5–1.5 Hz) increases at central locations over the course of development.

claimIn older adults, the coupling of spindles and slow oscillations (SOs) is reduced, and spindles tend to occur earlier in the slow oscillation phase compared to younger adults.

claimDubè et al. found that cortical thinning explains changes in sleep slow waves during adulthood.

claimCortical thinning is linked to changes in sleep slow waves during adulthood, according to a 2015 study in the Journal of Neuroscience.

referenceDuring slow-wave sleep, the brain exhibits slow oscillations and slow-wave activity that facilitate the transfer of newly acquired information from the hippocampus to the neocortex for long-term storage, according to Sridhar et al. (2023).

claimKetamine treatment in patients with major depressive disorder induces plasticity, as indicated by concomitant changes in Brain-Derived Neurotrophic Factor (BDNF) levels and sleep slow waves.
