    Novel analytical tools reveal that local synchronization of cilia coincides with tissue-scale metachronal waves in zebrafish multiciliated epithelia

    Christa Ringers, Stephan Bialonski ... Nathalie Jurisch-Yaksi
    Novel frequency-based analysis and computation modeling of cilia carpets reveals that tissue-scale metachronal coordination of cilia can arise even in the absence of global synchronization.

    Dendritic branch structure compartmentalizes voltage-dependent calcium influx in cortical layer 2/3 pyramidal cells

    Andrew T Landau, Pojeong Park ... Bernardo L Sabatini
    Elaborate dendritic branch patterns lead to a local and branch-specific reduction in impedance, which attenuates back-propagating action potentials and limits voltage-gated calcium influx.

    Intravital quantification reveals dynamic calcium concentration changes across B cell differentiation stages

    Carolin Ulbricht, Ruth Leben ... Anja E Hauser
    Heterogeneity in cytoplasmic calcium concentration alongside B cell activation and differentiation is measured intravitally using an interdisciplinary imaging approach and novel numerical analysis.

    Polycystin-2 is an essential ion channel subunit in the primary cilium of the renal collecting duct epithelium

    Xiaowen Liu, Thuy Vien ... David E Clapham
    The primary cilia polycystin proteins, polycystin-1 and polycystin-2, affect cilia length in the kidney collecting duct epithelia, but only polycystin-2 is required for the functional ion channel in this organelle.

    TTBK2 and primary cilia are essential for the connectivity and survival of cerebellar Purkinje neurons

    Emily Bowie, Sarah C Goetz
    Signaling at the primary cilium is important to sustain the morphology, connectivity, and survival of a key neural population within the brain.

    Dynein-2 intermediate chains play crucial but distinct roles in primary cilia formation and function

    Laura Vuolo, Nicola L Stevenson ... David J Stephens
    Genetic knock-outs of the dynein-2 intermediate chains reveals that both are essential for correct cilia function and transition zone organization, but play different functions in the assembly of dynein-2 motor and in primary cilia formation.

    Cholinergic modulation of hippocampal calcium activity across the sleep-wake cycle

    Heng Zhou, Kevin R Neville ... Stephen N Gomperts
    Dynamic calcium activity in the hippocampus changes markedly across behavioral and physiological states and depends on muscarinic acetylcholine receptor activation.

    Excitatory neurotransmission activates compartmentalized calcium transients in Müller glia without affecting lateral process motility

    Joshua M Tworig, Chandler J Coate, Marla B Feller
    During development, lateral processes of retinal Müller glia are highly motile, and this motility persists when retinal waves and calcium transients are blocked, suggesting that Müller glial morphology is established independent of neuronal activity.

    Efficient and accurate extraction of in vivo calcium signals from microendoscopic video data

    Pengcheng Zhou, Shanna L Resendez ... Liam Paninski
    A new open-source computational toolbox for processing in vivo microendoscopic calcium imaging data performs signal demixing and denoising much more accurately than previously available methods, significantly improving the utility of this imaging modality.
