    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.

    Cortical ChAT+ neurons co-transmit acetylcholine and GABA in a target- and brain-region-specific manner

    Adam J Granger et al.
    Most ChAT-expressing interneurons are a subset VIP+ interneurons that differentially release GABA and acetylcholine onto different post-synaptic targets, while a separate population of non-VIP ChAT+ neurons release acetylcholine in mPFC.

    Sleep is bi-directionally modified by amyloid beta oligomers

    Güliz Gürel Özcan et al.
    Amyloid beta, the major component of plaques in Alzheimer's disease, acutely and reversibly signals to modulate sleep as a function of oligomeric length, independently of neuronal loss.

    A non-mosaic transchromosomic mouse model of Down syndrome carrying the long arm of human chromosome 21

    Yasuhiro Kazuki et al.
    TcMAC21 is an appropriate “next gen” mouse model for DS research, and provides a proof of concept of using artificial chromosomes to generate non-mosaic humanized animal models of chromosome disorders.

    Dynamic behavior of the locus coeruleus during arousal-related memory processing in a multi-modal 7T fMRI paradigm

    Heidi IL Jacobs et al.
    By combining ultra-high-field imaging with physiological and saliva measures it is established that interactions between locus coeruleus, hippocampus and amygdala vary along emotional memory stages, putatively reflecting distinct cognitive states.

    Control of adaptive action selection by secondary motor cortex during flexible visual categorization

    Tian-Yi Wang et al.
    The secondary motor cortex causally contributes to flexible action selection during stimulus categorization with the representations of upcoming choice and sensory history regulated by the demand to remap stimulus–action association.

    Global sleep homeostasis reflects temporally and spatially integrated local cortical neuronal activity

    Christopher W Thomas et al.
    The global sleep homeostatic process tracks sleep-wake history by integrating local cortical neuronal activity over time and space, rather than directly reflecting changes in specific homeostatically regulated physiological variables.

    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.

    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.

    SynGAP isoforms differentially regulate synaptic plasticity and dendritic development

    Yoichi Araki et al.
    Detailed SYNGAP1 splice variant characterization uncovers distinct isoform functions and biochemical properties contributing to critical aspects of neurodevelopment, providing previously unknown isoform-level insight into SYNGAP1-related cognitive disorders.
