    Structural determinants of voltage-gating properties in calcium channels

    Monica L Fernández-Quintero, Yousra El Ghaleb ... Bernhard E Flucher
    Structure modeling, site-directed mutagenesis, and current recordings revealed the mechanism by which stabilization of voltage sensors in the resting and activated states determines the gating properties of the CaV1.1 calcium channel.

    Post-tetanic potentiation lowers the energy barrier for synaptic vesicle fusion independently of Synaptotagmin-1

    Vincent Huson, Marieke Meijer ... Lennart Niels Cornelisse
    Modulation of the energy barrier for membrane fusion is a common mechanism by which sensors in the synapse produce supralinear calcium dependence of vesicle release and short-term synaptic potentiation.

    Spatially compartmentalized phase regulation of a Ca2+-cAMP-PKA oscillatory circuit

    Brian Tenner, Michael Getz ... Jin Zhang
    Nanodomain clustering of cAMP effectors represents a novel mechanism of cAMP compartmentation within an oscillatory signaling circuit.

    Slow presynaptic mechanisms that mediate adaptation in the olfactory pathway of Drosophila

    Carlotta Martelli, André Fiala
    Slow presynaptic depression in olfactory receptor neurons rescales combinatorial odor representations in postsynaptic neurons and mediates the encoding of stimulus mean and variance.

    A theory of synaptic transmission

    Bin Wang, Olga K Dudko
    The analytic theory establishes the general principles of synaptic transmission, enables extraction of microscopic parameters of synaptic fusion machinery from experiments, and links molecular constituents to synaptic function.

    Live imaging reveals the cellular events downstream of SARM1 activation

    Kwang Woo Ko, Laura Devault ... Aaron DiAntonio
    Axon degeneration occurs via an ordered sequence of events downstream of SARM1 that proceeds from ATP loss, to defects in mitochondrial movement and depolarization, followed by calcium influx, phosphatidylserine externalization, loss of membrane permeability, and ending with catastrophic axonal self-destruction.

    Keratinocytes contribute to normal cold and heat sensation

    Katelyn E Sadler, Francie Moehring, Cheryl L Stucky
    Purinergic keratinocyte-to-sensory neuron signaling is a ubiquitous amplification mechanism that is required for normal mechanical, cold, and heat sensation in vivo.

    Dendritic coincidence detection in Purkinje neurons of awake mice

    Christopher J Roome, Bernd Kuhn
    Simultaneous voltage and calcium two-photon imaging of Purkinje neuron dendrites in awake mice reveals multiple interplaying mechanisms underlying sensory-evoked dendritic coincidence detection of parallel fiber and climbing fiber input.

    Nanodomain coupling explains Ca2+ independence of transmitter release time course at a fast central synapse

    Itaru Arai, Peter Jonas
    Ca2+ channels and release sensors at a fast central synapse are tightly coupled, which minimizes the effect of extracellular Ca2+ concentration on the timing of transmitter release.
