    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.

    Autocatalytic microtubule nucleation determines the size and mass of Xenopus laevis egg extract spindles

    Franziska Decker et al.
    Quantitative microscopy and theory show that the size of Xenopus laevis egg extract spindles is controlled by a spatially-regulated autocatalytic growth mechanism driven by microtubule-stimulated microtubule nucleation.

    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.

    27 T ultra-high static magnetic field changes orientation and morphology of mitotic spindles in human cells

    Lei Zhang et al.
    An ultra-high static magnetic field changes mitotic spindle orientation in cells by exerting magnetic torques on both microtubules and chromosomes.

    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.

    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.

    Using subthreshold events to characterize the functional architecture of the electrically coupled inferior olive network

    Yaara Lefler et al.
    Non-synaptic electrical events recorded simultaneously from pairs of neurons in the inferior olive nucleus enables accurate estimation of the size and of the clustered organization of the electrically coupled network.

    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.
