Sleep to Think: Multimodal Mechanisms Linking Sleep, Learning, and Performance

Sleep is not merely a passive state but a dynamic process fundamental to learning, memory consolidation, and cognitive performance. During sleep, the brain undergoes remarkable transformations—reorganizing neural circuits, strengthening newly acquired memories, and clearing metabolic waste accumulated during wakefulness. Decades of research have established that adequate sleep enhances learning capacity, improves problem-solving, and optimizes performance across academic, athletic, and professional domains. Conversely, sleep deprivation impairs attention, working memory, and executive function. Yet the precise multimodal mechanisms linking sleep architecture, electrophysiological activity, neurochemical processes, and behavioral outcomes remain incompletely understood. Recent advances in polysomnography, neuroimaging, electrophysiology, computational modeling, and biomarker assessment have enabled more sophisticated investigation of sleep-dependent learning and performance. Understanding these mechanisms across the lifespan—from infancy through aging—is essential for optimizing human cognition and performance.This Research Topic aims to comprehensively examine the multimodal neurobiological mechanisms by which sleep facilitates learning, memory consolidation, and cognitive performance. We seek to address critical questions: How do sleep stage-specific processes (REM sleep, NREM sleep, slow-wave sleep) differentially support learning and memory? What are the roles of sleep spindles, slow oscillations, and other electrophysiological signatures in memory replay and systems consolidation? How do sleep-dependent changes in synaptic strength, protein synthesis, and gene expression contribute to long-term learning? What neurochemical systems (acetylcholine, norepinephrine, dopamine) regulate sleep-dependent memory processing? How do individual differences in sleep architecture, circadian timing, and sleep need predict learning outcomes and performance? Can targeted sleep interventions or stimulation techniques enhance learning efficiency? By integrating neuroscience, psychology, physiology, and behavioral research, this collection will illuminate the fundamental sleep-learning-performance nexus and provide evidence-based insights for optimizing cognitive outcomes across contexts and populations.We welcome original research, reviews, perspectives, and methodological innovations investigating the links between sleep and learning, memory, or performance.
