Sleep and Wakefulness Research

The paper investigates offline neural activity changes after learning and relearning using resting state fMRI, finding continued task-related activity and compensatory connectivity after sleep deprivation.

This study shows that different types of waking experiences in mice affect sleep pressure differently, with task-based wakefulness reducing sleep need more than exploratory behavior.

This study identifies determinants of subjective sleep perception through high-density EEG recordings and interviews during serial awakenings in individuals with and without sleep misperception.

The paper examines EEG microstate dynamics during post-encoding rest and finds increased microstate D and decreased microstate C, associated with memory consolidation and encoding strength.

The paper shows sleep spindles help consolidate weakly encoded memories, reducing forgetting rates compared to staying awake.

This study identifies a genetic association between Kleine-Levin Syndrome and variants in the TRANK1 gene, with increased risk linked to birth difficulties.

The paper builds a neural mass model of PGO waves to show how sleep stages influence cortical plasticity through bidirectional synaptic changes.

This study investigates whether sleep enhances visual disparity discrimination and its generalization across the vertical meridian, finding no significant effect of sleep on consolidation of this perceptual skill.

The paper develops a model to predict brain temperature in mice based on sleep-wake state and time-of-day, finding sleep-wake sequences explain most of the variance.

This study identifies medulla glutamatergic neurons projecting to the preoptic area that control wake-sleep transitions through chemogenetic and optogenetic manipulations.

This study shows that splitting sleep between night and a daytime nap improves memory and reduces sleep pressure in adolescents.

This study examines how lipopolysaccharide (LPS) affects electrophysiological activity in mice, linking inflammation to changes in slow wave activity and potential delirium mechanisms.

The paper investigates daily orexinergic modulation of the rat superior colliculus, showing circadian coordination between orexin input and visual system activity.

The paper identifies ISWI as a chromatin remodeler required for adult sleep in Drosophila, with distinct developmental roles in sleep and other behaviors.

The paper examines how auditory neural responses change across the sleep-wake cycle, finding state- and stimulus-dependent reorganization of auditory processing.

The paper analyzes spindles in humans to show they create spatiotemporal patterns of neuronal co-firing that may support memory consolidation during NREM sleep.

The paper examines how stress affects the relationship between slow wave sleep and emotional memory, finding that slow oscillation-spindle coupling negatively correlates with memory in stressed individuals.

The paper investigates how stress and sleep affect memory of a social stressor environment, finding that NREM sleep physiology, not stress reactivity, is linked to memory retention in non-stressed individuals.

The paper presents a matrix-based method to infer arousal state by integrating neural, metabolic, and immune system data.

The paper shows that sleep does not enhance forgetting of large amounts of declarative memory, contradicting the hypothesis that sleep increases forgetting at high information loads.

This study investigates whether sleep and wake states drive changes in neocortical synaptic strength in juvenile rats, finding no significant changes in synaptic strength across these states.

The paper shows that multiple memories can be reactivated during sleep without reducing their consolidation benefits, suggesting parallel memory processing during sleep.

This study investigates the effects of high-frequency DBS on sleep-wake characteristics in rats, finding that it modulates sleep intensity without altering sleep proportions or stability.

The paper identifies a neural circuit in zebrafish where neuropeptide VF neurons promote sleep by activating serotonergic raphe nuclei.

The paper analyzes iEEG power and coherence in rats across behavioral states, cortical areas, and light/dark phases, finding state- and area-dependent changes and REM sleep-specific hemispheric differences.

This study shows that CREB is necessary in forebrain neurons for maintaining wakefulness but not in the locus coeruleus.

The paper identifies vGAT neurons in the zona incerta that are most active during NREM and REM sleep using in vivo calcium imaging.
