    Sleep spindles mediate hippocampal-neocortical coupling during long-duration ripples

    Hong-Viet Ngo et al.
    Triggered by (long-duration) hippocampal ripples, spindles facilitate communication between the hipppocampus and neocortex during natural sleep.

    mPFC spindle cycles organize sparse thalamic activation and recently active CA1 cells during non-REM sleep

    Carmen Varela, Matthew A Wilson
    Sleep spindles provide a temporal framework to organize the reactivation of behaviorally relevant CA1 cells and sparsely active cells in the limbic thalamus.

    Rotating waves during human sleep spindles organize global patterns of activity that repeat precisely through the night

    Lyle Muller et al.
    A phase-based analysis reveals wave-like spatiotemporal organization of the human sleep spindle, a brain oscillation critical to sleep-dependent memory consolidation, and elucidates its role in coordinating activity of neural networks distributed across the cortex.

    Slow oscillation-spindle coupling predicts enhanced memory formation from childhood to adolescence

    Michael A Hahn et al.
    An individualized cross-frequency coupling approach identified slow oscillation-spindle coupling strength as a novel mechanism that mediates memory formation during cortical maturation.

    A nap to recap or how reward regulates hippocampal-prefrontal memory networks during daytime sleep in humans

    Kinga Igloi et al.
    Sleep plays a critical role in the selectivity of memory by promoting the retention of important memories at the expense of less relevant ones.

    Thalamic reticular control of local sleep in mouse sensory cortex

    Laura MJ Fernandez et al.
    Local cortical sleep features arise subcortically due to heterogeneous burst discharge in neurons of a sleep rhythm pacemaker previously thought to act uniformly.

    Cellular and neurochemical basis of sleep stages in the thalamocortical network

    Giri P Krishnan et al.
    A computational model of the thalamocortical network explains sleep stages by the coordinated variations in the level of neuromodulators and predicts differences of sleep pattern in human, cat and mouse recordings.

    Selectively driving cholinergic fibers optically in the thalamic reticular nucleus promotes sleep

    Kun-Ming Ni et al.
    Cholinergic system play an important role in waking-to-sleep cycles and in sleep stabilization.

    Frequency-selective control of cortical and subcortical networks by central thalamus

    Jia Liu et al.
    Central thalamus relay neurons dynamically switch the activity of cortical and subcortical networks at distinct frequencies, providing a mechanism for this region's role in arousal regulation.

    Neural signatures of α2-Adrenergic agonist-induced unconsciousness and awakening by antagonist

    Jesus Javier Ballesteros et al.
    Instant performance recovery is possible following general anesthesia-induced unconsciousness using antagonist, and the brain dynamics return abruptly to the awake state without intermediate recovery states.
