    Chemogenetic inhibition of the medial prefrontal cortex reverses the effects of REM sleep loss on sucrose consumption

    Kristopher McEown et al.
    Loss of REM sleep increases sucrose and fat consumption in mice; and inhibiting the prefrontal cortex reverses the increased consumption of sucrose, but not fat, following REM sleep loss.

    Frontal beta-theta network during REM sleep

    Sujith Vijayan et al.
    Two regions of the frontal lobe – the anterior cingulate cortex and, unexpectedly, the dorsolateral prefrontal cortex – show coordinated rhythmic activity during REM sleep.
    1. Neuroscience

    Network-wide reorganization of procedural memory during NREM sleep revealed by fMRI

    Shahabeddin Vahdat et al.
    Non-REM sleep is essential in the restoration of initial motor memory trace and gradual reorganization of newly-learned information underlying human procedural memory consolidation.
    1. Neuroscience

    Neurovascular coupling and bilateral connectivity during NREM and REM sleep

    Kevin L Turner et al.
    Sleep-related hemodynamic signals are much larger than those in the awake brain, so it is crucial to monitor the arousal state during studies of spontaneous activity.
    1. Neuroscience

    Cold-inducible RNA-binding protein (CIRBP) adjusts clock-gene expression and REM-sleep recovery following sleep deprivation

    Marieke MB Hoekstra et al.
    The temperature-sensitive protein CIRBP contributes to the effect of sleep loss on the molecular circadian clock.
    1. Neuroscience

    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.
    1. Neuroscience

    An electrophysiological marker of arousal level in humans

    Janna D Lendner et al.
    Non-oscillatory brain activity can be used to monitor arousal levels during both NREM and REM sleep as well as under general anesthesia with propofol.
    1. Neuroscience

    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.
    1. Neuroscience

    GABA neurons in the ventral tegmental area regulate non-rapid eye movement sleep in mice

    Srikanta Chowdhury et al.
    Functional identification of GABAergic neurons in the ventral tegmental area as a important neuronal subpopulation regulating non-rapid eye movement (NREM) sleep in mice.
    1. Neuroscience

    Coupling between motor cortex and striatum increases during sleep over long-term skill learning

    Stefan M Lemke et al.
    Sleep spindles, distinctive brain activity patterns occurring in non-REM sleep, modify cross-area connectivity in the motor network relevant for behavioral flexibility, impacting subsequent behavior.
