    Non-rapid eye movement (NREM) sleep is associated with increased cerebrospinal fluid (CSF) flow in mammals, but this link has not been studied in birds. Here, the authors show that in pigeons, REM sleep is associated with activation of visual brain regions and a drop in CSF flow, suggesting that REM sleep functions occur at the expense of waste clearance during NREM sleep.

    Grammar learning requires memory for temporally organised, rule-based patterns in speech. Here, the authors use event-related potentials to show that 6 to 8 month-old infants can form memory of dependencies between nonadjacent elements in sentences of an unknown language, regardless of whether they nap or stay awake after encoding.

    Microglia survey the parenchyma, which leads to morphology changes over time. Here the authors show using 2 photon imaging of microglia in vivo that sleep modulates microglial morphodynamics through Cx3cr1 signaling.

    The preoptic area (POA) is critical for sleep regulation but its role in acute, non-circadian, light effects on sleep are unclear. The authors show that intrinsically photosensitive retinal ganglion cells provide substantial input into the POA and through these modulate the amount of non-rapid eye movement (NREM) sleep.

    Thalamic head direction (HD) cells are necessary to establish spatial maps in the hippocampus. Here, the authors show that HD cells tuned to a particular direction are coupled to individual hippocampal ripple events during sleep, suggesting an influence of the replay of specific trajectories during sleep memory consolidation.

    NREM sleep in rodents is characterized by internal dynamics in the form of UP/DOWN states in the neocortex and SWRs in the hippocampus. Here, the authors report that a mean field model with excitable dynamics captures the transition probabilities between these states from rodent sleep data.

    In addition to circadian and homoeostatic drives, motivational levels influence sleep−wake cycles. Here the authors demonstrate that adenosine receptor-expressing neurons in the nucleus accumbens core that project to the ventral pallidum are inhibited by motivational stimuli and are causally involved in the control of slow-wave sleep.

    Sleep patterns vary and are associated with health and disease. Here Purcellet alcharacterize sleep spindle activity in 11,630 individuals and describe age-related changes, genetic influences, and possible confounding effects, serving as a resource for further understanding the physiology of sleep.

    During non-REM sleep, the thalamus produces spindles and the cortex produces downstates, but the interaction between these two areas in these sleep phenomena is not understood. Here, authors describe the dynamic loop between the thalamus and cortex that organizes the production of spindles and downstates in the human brain.
