    Inferring circuit mechanisms from sparse neural recording and global perturbation in grid cells

    John Widloski, Michael P Marder, Ila R Fiete
    A novel experimental method and analysis is conceived, based on perturbation and sparse recording, to elucidate the circuit structure and mechanisms underlying the responses of grid cells.

    Characterization of developmental and molecular factors underlying release heterogeneity at Drosophila synapses

    Yulia Akbergenova, Karen L Cunningham ... J Troy Littleton
    Active zone release probability is correlated with calcium channel density and calcium influx at single release sites, with release strength increasing in an activity-dependent manner during synapse maturation.

    Presenilin mutations deregulate mitochondrial Ca2+ homeostasis and metabolic activity causing neurodegeneration in Caenorhabditis elegans

    Shaarika Sarasija, Jocelyn T Laboy ... Kenneth R Norman
    In C. elegans, presenilin functions, independent of its gamma-secretase proteolytic activity, to regulate mitochondrial metabolism by controlling ER-mitochondrial calcium transfer and, even in the absence of Abeta signaling, loss of this activity leads to neurodegeneration.

    A mechanism for exocytotic arrest by the Complexin C-terminus

    Mazen Makke, Maria Mantero Martinez ... Dieter Bruns
    The far C-terminal domain of CpxII interferes with SNARE assembly and thereby arrests tonic exocytosis.

    Pre-post synaptic alignment through neuroligin-1 tunes synaptic transmission efficiency

    Kalina T Haas, Benjamin Compans ... Eric Hosy
    Neuroligin 1 is a critical adhesion molecule which organizes AMPA receptor nanodomains in close vicinity to pre-synaptic release sites, and whose genetic or chemical disruption severely impairs synaptic transmission properties.

    Loss of Atoh1 from neurons regulating hypoxic and hypercapnic chemoresponses causes neonatal respiratory failure in mice

    Meike E van der Heijden, Huda Y Zoghbi
    Atoh1 promotes the development of two different neural circuits involved in hypoxic and hypercapnic respiratory responses that together are essential for neonatal respiratory drive and survival.

    Rap2 and TNIK control Plexin-dependent tiled synaptic innervation in C. elegans

    Xi Chen, Akihiro CE Shibata ... Kota Mizumoto
    Plexin controls the spatial distribution of synapses by locally inhibiting Rap2 small GTPase activity along the axon, and a Rap2 effector, TNIK, which also plays a key role in inhibiting synapse number.

    Content-specific activity in frontoparietal and default-mode networks during prior-guided visual perception

    Carlos González-García, Matthew W Flounders ... Biyu J He
    Prior experience alters content-specific neural representations of visual input in frontoparietal and default-mode networks.

    Thioredoxin shapes the C. elegans sensory response to Pseudomonas produced nitric oxide

    Yingsong Hao, Wenxing Yang ... Joshua M Kaplan
    C. elegans utilizes bacterially produced nitric oxide as a sensory cue to elicit avoidance of pathogenic bacteria.

    Adaptation to constant light requires Fic-mediated AMPylation of BiP to protect against reversible photoreceptor degeneration

    Andrew T Moehlman, Amanda K Casey ... Helmut Krämer
    Tuning of BiP activity by Fic-mediated AMPylation is required for Drosophila photoreceptor plasticity and attenuation of the unfolded protein response.
