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

    Liyi Li, Sébastien Sultan ... Josef Bischofberger
    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.

    Neto auxiliary proteins control both the trafficking and biophysical properties of the kainate receptor GluK1

    Nengyin Sheng, Yun S Shi ... Roger A Nicoll
    Auxiliary subunits Neto1 and Neto2 regulate the GluK1 receptor targeting to excitatory silent synapses through different molecular mechanisms and also modify receptor biophysics through distinct mechanisms.

    Mitochondrial support of persistent presynaptic vesicle mobilization with age-dependent synaptic growth after LTP

    Heather L Smith, Jennifer N Bourne ... Kristen M Harris
    Three-dimensional electron microscopy (3DEM) demonstrates the dependence on presynaptic mitochondria for vesicle mobilization as dendritic spines are silently added at P15 or synapses are silently enlarged in adults after long-term potentiation.

    GABABR silencing of nerve terminals

    Daniel C Cook, Timothy A Ryan
    Single bouton measurements of calcium influx shows that activating GABAB receptors at nerve terminals can lead to complete inhibition of calcium entry when one is operating at the physiological setpoint of extracellular calcium concentration.

    Clusters of synaptic inputs on dendrites of layer 5 pyramidal cells in mouse visual cortex

    Onur Gökçe, Tobias Bonhoeffer, Volker Scheuss
    A combination of optogenetics and 2-photon calcium imaging reveals spatial prerequisites for non-linear synaptic summation within a defined cortical connection.

    Experience-dependent weakening of callosal synaptic connections in the absence of postsynaptic FMRP

    Zhe Zhang, Jay R Gibson, Kimberly M Huber
    Postnatal, postsynaptic loss of FMRP specifically weakens callosal synaptic inputs onto L2/3 pyramidal neurons, in requirement ofnormal sensory experience, through downregulating AMPA receptor transmission and without affecting local synaptic inputs during cortical circuit development.

    Retinoic acid-gated BDNF synthesis in neuronal dendrites drives presynaptic homeostatic plasticity

    Shruti Thapliyal, Kristin L Arendt ... Lu Chen
    Synaptic silencing-induced homeostatic enhancement of presynaptic glutamate release is mediated by the postsynaptic retinoic acid-dependent brain-derived neurotrophic factor (BDNF) synthesis from dendritically targeted BDNF transcripts, leading to retrograde activation of presynaptic tropomyosin receptor kinase B receptors.

    Self-organization of in vitro neuronal assemblies drives to complex network topology

    Priscila C Antonello, Thomas F Varley ... Jean Faber
    Effectively connected neurons self-organize forming networks with a small-world architecture composed of modules, with most likely few and nearby neurons, integrated by more topologically important and high firing rate neurons.

    Basolateral amygdala oscillations enable fear learning in a biophysical model

    Anna Cattani, Don B Arnold ... Nancy Kopell
    Computational modeling suggests that the BLA is capable of producing the recorded LFP rhythms via interactions of interneuron subtypes, and that those rhythms may be necessary for associative learning.

    Ultrastructural effects of sleep and wake on the parallel fiber synapses of the cerebellum

    Sophia S Loschky, Giovanna Maria Spano ... Chiara Cirelli
    In the mouse cerebellum, the number of branched synapses is reduced in half after sleep compared to after wake.
