    Chronic 2P-STED imaging reveals high turnover of dendritic spines in the hippocampus in vivo

    Thomas Pfeiffer et al.
    Super-resolution STED microscopy is demonstrated for the first time in the deeply embedded mouse hippocampus in vivo, revealing direct evidence for an unprecedentedly high level of synapse remodeling in a brain structure closely associated with memory processing.

    Uncovering temporal structure in hippocampal output patterns

    Kourosh Maboudi et al.
    Machine learning models of coordinated hippocampal ensemble activity during sharp wave ripple activity encode structure that mirrors the place cell map expressed during exploration, and enable a new paradigm for analyzing and understanding this offline activity.

    BMP and FGF signaling interact to pattern mesoderm by controlling basic helix-loop-helix transcription factor activity

    Richard H Row et al.
    Interplay between FGF-induced bHLH transcription factors and BMP-induced bHLH inhibitory id genes govern mesodermal cell fate choice along the mediolateral axis in both zebrafish and mouse.

    Striatal action-value neurons reconsidered

    Lotem Elber-Dorozko, Yonatan Loewenstein
    The numerous reports in support of action-value representation in the striatum are based on statistical analyses that are subject to two critical confounds and, thus, this long-held belief of striatal action-value representation should be retested using different experiments and analyses.

    Lamellar projections in the endolymphatic sac act as a relief valve to regulate inner ear pressure

    Ian A Swinburne et al.
    The pressure of fluid in the inner ear is controlled by opening of cellular valves in the endolymphatic sac to allow for regulated transepithelial fluid flow.

    Plasmacytoid dendritic cells control dengue and Chikungunya virus infections via IRF7-regulated interferon responses

    Brian Webster et al.
    In vivo study of arbovirus infections reveals the dominant role of pDC IRF7-signaling in directing both type I and II IFN responses, and leading to viral control.

    Developmental deprivation-induced perceptual and cortical processing deficits in awake-behaving animals

    Justin D Yao, Dan H Sanes
    Developmental hearing loss causes perceptual deficits that are best explained by degraded auditory cortical encoding that is recorded during task performance.

    A label-free approach to detect ligand binding to cell surface proteins in real time

    Verena Burtscher et al.
    Binding of a charged small molecule to a membrane protein changes the amplitude of the apparent membrane capacitance by changing the charge density at the surfaces of the membrane.

    Coordination of robust single cell rhythms in the Arabidopsis circadian clock via spatial waves of gene expression

    Peter D Gould et al.
    Single cell analysis reveals how period differences between cells and cell-to-cell coupling generates the spatial structure of the plant circadian clock.
