What the literature leaves open

  • Investigate the mechanism(s) underpinning the support of sleep on social-cognitive foundations of communication, - Examine the effect of sleep on partner-specific common ground in a larger sample, - Explore the impact of sleep on other aspects of social cognition

  • Future studies should consider incorporating composite PGSs for OSA, COMISA, and chronobiological misalignment to refine predictive models, - Recognition of the epigenetic plasticity of sleep-related pathways introduces new possibilities for preemptive and therapeutic modulation

    Integrating sleep-related breathing disorders and epigenetics into the genetic landscape of sleep disturbances in psychotic disorders · 2025 · DOI

  • the current framework for understanding sleep in psychosis does not adequately account for sleep-related breathing disorders and epigenetic regulation - there is a need for more accurate stratification of sleep phenotypes and refinement of risk prediction models - the development of targeted interventions that improve outcomes for individuals with psychotic disorders is limited by the current understanding of sleep disturbances

    Integrating sleep-related breathing disorders and epigenetics into the genetic landscape of sleep disturbances in psychotic disorders · 2025 · DOI

  • Investigate the contribution of sleep vagal activity to the consolidation of other types of emotional memories - Examine the relationship between REM sleep and extinction memory in individuals with PTSD - Explore the potential therapeutic applications of targeting REM sleep and vagal activity in the treatment of PTSD and other anxiety-related disorders

    REM disruption and REM vagal activity predict extinction recall in trauma-exposed individuals · 2024 · DOI

  • Sleep deprivation is a potent, rapid-acting therapeutic intervention for major depressive disorder, yet its underlying neural mechanisms remain poorly understood, hindering the development of predictive biomarkers.

  • Whether this process requires mature episodic memory expression during early development remains unclear.

  • Closed-loop auditory stimulation (CLAS) of sleep slow oscillations enhances memory consolidation in healthy individuals, but its efficacy in AD remains unknown.

  • How the brain compensates for sleep deprivation (SD) by generating recovery sleep (RS) is not understood.

    Wake-active brainstem GABA neurons signal sleep pressure by upregulating AMPA receptors to drive recovery sleep · 2026 · DOI

  • Homeostatic sleep regulation is essential for optimizing the amount and timing of sleep for its revitalizing function, but the mechanism underlying sleep homeostasis remains poorly understood.

    Activation of locus coeruleus noradrenergic neurons rapidly drives homeostatic sleep pressure · 2025 · DOI

  • Collectively, our findings suggest that subjective sleep assessments alone are insufficient for evaluating sleep health and that health checkups and advice based on sleep EEG measurements may be useful in improving sleep habits and for early detection of sleep disorders.

    Discrepancies between subjective and objective sleep assessments revealed by in-home electroencephalography during real-world sleep · 2025 · DOI

  • While cerebrospinal fluid (CSF) during sleep has been implicated in metabolic waste reduction in animals, how CSF dynamics are driven in the healthy human brain during deep sleep remains elusive.

    Human deep sleep facilitates cerebrospinal fluid dynamics linked to spontaneous brain oscillations and neural events · 2025 · DOI

  • Sleep supports memory consolidation, but the specific roles of different sleep stages in this process remain unclear.

    Both slow wave and rapid eye movement sleep contribute to emotional memory consolidation · 2025 · DOI

  • Together, our findings indicate that spiral waves are a defining spatiotemporal feature of N2 sleep and play a crucial role in memory consolidation, offering a promising avenue for further research into sleep-dependent memory processing.

    Spatiotemporal dynamics of sleep spindles form spiral waves that predict overnight memory consolidation and age-related memory decline · 2025 · DOI

  • A growing body of evidence has demonstrated that sleep spindles occurring during stage 2 non-rapid-eye-movement (N2) sleep often organize into travelling waves, but the spatiotemporal dynamics of these waves and their functional significance remain unclear.

  • Objective measures of nighttime sleep and daytime sleepiness are lacking with oxybates in IH.

  • Finally, we propose key open questions that need to be addressed in future studies.
