    Structural insights into the Ca2+-dependent gating of the human mitochondrial calcium uniporter

    Yan Wang, Yan Han ... Youxing Jiang
    Cryo-EM structures of human MCU-EMRE-MICU1-MICU2 complex in the apo and Ca2+-bound states reveal how MICU1 and MICU2 impart their gating function to the mitochondrial calcium uniporter.

    Structural basis of Ca2+-dependent activation and lipid transport by a TMEM16 scramblase

    Maria E Falzone, Jan Rheinberger ... Alessio Accardi
    Structures of a TMEM16 phospholipid scramblase reveal that its Ca2+-dependent activation entails global conformational changes and how these rearrangements affect the membrane to enable transbilayer lipid transfer.

    Cryo-EM structures and functional characterization of the murine lipid scramblase TMEM16F

    Carolina Alvadia, Novandy K Lim ... Cristina Paulino
    While activated by a common mechanism, both functions in TMEM16F - lipid scrambling and ion conduction - are likely mediated by alternate protein conformations that are at equilibrium in the ligand-bound state.

    Ca2+ inactivation of the mammalian ryanodine receptor type 1 in a lipidic environment revealed by cryo-EM

    Ashok R Nayak, Montserrat Samsó
    Cryogenic electron microscopy of the ryanodine receptor 1 at near-atomic resolution reveals a calcium-inactivated conformation and uncovers a conserved lipid-binding site.

    Noisy neuronal populations effectively encode sound localization in the dorsal inferior colliculus of awake mice

    Juan Carlos Boffi, Brice Bathellier ... Robert Prevedel
    Bespoke volumetric calcium imaging, validated with neuropixels recordings, evidence a population code for sound azimuth at the dorsal cortex of the inferior colliculus, with a contribution of noise correlations.

    Proximal CA1 20–40 Hz power dynamics reflect trial-specific information processing supporting nonspatial sequence memory

    Sandra Gattas, Gabriel A Elias ... Norbert J Fortin
    The hippocampal CA1 20–40 Hz rhythm is associated with nonspatial sequence memory processing and may contribute to the role of the hippocampus in processing temporal relationships among events.

    A non-conducting role of the Cav1.4 Ca2+ channel drives homeostatic plasticity at the cone photoreceptor synapse

    J Wesley Maddox, Gregory J Ordemann ... Amy Lee
    In congenital stationary night blindness type 2, Cav3 channels may maintain cone synaptic output and visual function provided that the nonconducting role of Cav1.4 in cone synaptogenesis remains intact.

    Hippocampal ensemble dynamics timestamp events in long-term memory

    Alon Rubin, Nitzan Geva ... Yaniv Ziv
    Temporally close events share a common timestamp regardless of the spatial context in which they occur.

    Time- and polarity-dependent proteomic changes associated with homeostatic scaling at central synapses

    Christoph T Schanzenbächer, Julian D Langer, Erin M Schuman
    Metabolic labelling and quantitative proteomics reveal the temporal evolution of cellular and neuronal responses to global activity manipulations.

    State-dependent coupling of hippocampal oscillations

    Brijesh Modi, Matteo Guardamagna ... Francesco P Battaglia
    A novel analytical framework for investigation of simultaneously occurring brain oscillations (from either single or multiple brain areas) and how it modulates the underlying neuronal population during sleep and wakefulness (or other behavioral tasks).
