    Spatiotemporal dynamics of multi-vesicular release is determined by heterogeneity of release sites within central synapses

    Dario Maschi, Vitaly A Klyachko
    Release site heterogeneity represents a previously unknown level of structural and functional organization within individual active zones in central synapses, which determines the spatiotemporal dynamics of multi-vesicular release.

    Spatial cell firing during virtual navigation of open arenas by head-restrained mice

    Guifen Chen et al.
    A mouse virtual reality system is presented which allows normal spatial behavior and place, grid and head-direction cell firing patterns in 2-D arenas, and is compatible with electrophysiology and multi-photon imaging.

    Waves of actin and microtubule polymerization drive microtubule-based transport and neurite growth before single axon formation

    Amy M Winans et al.
    Waves of polymerizing actin work in concert with microtubule polymerization to lay down more microtubules tracks and transiently increase microtubule-based transport into the growing neurite.

    Human pyramidal to interneuron synapses are mediated by multi-vesicular release and multiple docked vesicles

    Gábor Molnár et al.
    The compactness of synaptic release sites coupled with their four-fold number in humans compared to rats provides unprecedented scaleability in operation of human synapses.

    Properties of multivesicular release from mouse rod photoreceptors support transmission of single-photon responses

    Cassandra L Hays et al.
    To improve the reliability of transmitting small single-photon voltage responses, rod photoreceptor cells release synaptic vesicles in regularly timed multivesicular events that are exquisitely sensitive to small voltage changes.

    The retromer complex safeguards against neural progenitor-derived tumorigenesis by regulating Notch receptor trafficking

    Bo Li et al.
    The retromer complex serves as a bomb squad to retrieve and disarm the potentially harmful pool of Notch receptors in a timely manner and thereby safeguards against brain tumor formation.

    Optical detection of three modes of endocytosis at hippocampal synapses

    Natali L Chanaday, Ege T Kavalali
    Single synaptic vesicle imaging shows that kinetically distinct endocytic pathways are differentially regulated by calcium and temperature, and influence the fidelity of synaptic vesicle protein retrieval.

    Origin and evolution of the nuclear auxin response system

    Sumanth K Mutte et al.
    The system that controls gene expression by the plant signaling molecule auxin has deep evolutionary roots, and stepwise increases in system complexity shaped the highly diverse auxin response in land plants.

    Cortex-wide BOLD fMRI activity reflects locally-recorded slow oscillation-associated calcium waves

    Miriam Schwalm et al.
    Locally recorded calcium events related to slow wave activity show a global cortical fMRI BOLD correlate, establishing a direct relation between a basic neurophysiological signal and the macroscopic perspective of pre-clinical fMRI.

    Exosomes mediate horizontal transmission of viral pathogens from insect vectors to plant phloem

    Qian Chen et al.
    An important rice reovirus hijacks exosomes to traverse the apical plasmalemma into saliva-stored cavities in the salivary glands of insect vectors, facilitating viral horizontal transmission into rice phloem.
