    A genetic basis for molecular asymmetry at vertebrate electrical synapses

    Adam C Miller et al.
    Electrical synapses are neuronal, gap-junction-based connections found throughout the nervous system that, in the escape circuit of zebrafish, are composed of molecularly distinct pre- and postsynaptic junction forming proteins that are required for behavioral performance.

    Co-agonists differentially tune GluN2B-NMDA receptor trafficking at hippocampal synapses

    Joana S Ferreira et al.
    D-serine has a major role in the regulation of NMDA receptors not only contributing to its activation as the receptors co-agonist, but also by regulating specifically GluN2B-NMDA receptor trafficking and synaptic content at developing hippocampal synapses.

    Astrocytes contribute to synapse elimination via type 2 inositol 1,4,5-trisphosphate receptor-dependent release of ATP

    Junhua Yang et al.
    Astrocytes regulate the pruning of excitatory synapses during early life through ATP signaling.

    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.

    Similar synapse elimination motifs at successive relays in the same efferent pathway during development in mice

    Shu-Hsien Sheu et al.
    A similar pattern of developmental synaptic refinement leads two consecutive synaptic relays to have the same organization suggesting that some general principle of neural organization is at play.

    Analysis of SUMO1-conjugation at synapses

    James A Daniel et al.
    Analyses using His6-HA-SUMO1 and SUMO1 KO mice indicate that SUMO1 modification of synaptic proteins is either absent or cannot be detected in brain and cultured neurons.

    Adaptive learning and decision-making under uncertainty by metaplastic synapses guided by a surprise detection system

    Kiyohito Iigaya
    Computational modeling offers an explanation for why animals learn more quickly or slowly when their environment becomes more variable or stable.

    Silent synapses generate sparse and orthogonal action potential firing in adult-born hippocampal granule cells

    Liyi Li et al.
    Young neurons of the adult hippocampus are synaptically activated by a small group of non-overlapping afferent excitatory fibers, due to high synaptic gain and sparse connectivity, important for sparse and orthogonal coding during hippocampal information processing.

    Arf6 regulates the cycling and the readily releasable pool of synaptic vesicles at hippocampal synapse

    Erica Tagliatti et al.
    The small GTPase Arf6 plays a role in setting the size of the readily releasable pool of synaptic vesicles and in the definition of the recycling route for endocytosed vesicles.

    Distinct structural and catalytic roles for Zap70 in formation of the immunological synapse in CTL

    Misty R Jenkins et al.
    Inhibition of the catalytic activity of the Zap70 kinase reveals that discrete TCR-regulated events control the remodelling of the actin cytoskeleton when the cytotoxic T cell interacts with its target.
