    The structure of the COPI coat determined within the cell

    Yury S Bykov, Miroslava Schaffer ... John AG Briggs
    Cryo-electron tomography of COPI vesicles in the Golgi reveals coat structure, disassembly dynamics, cargo binding, and morphological variability.

    Autophagic cell death is dependent on lysosomal membrane permeability through Bax and Bak

    Jason Karch, Tobias G Schips ... Jeffery D Molkentin
    Molecular pathways controlling autophagic cell death are regulated at the level of the lysosome through the activity of the pro-death Bcl-2 family member Bax/Bak.

    Systematic proteomic analysis of LRRK2-mediated Rab GTPase phosphorylation establishes a connection to ciliogenesis

    Martin Steger, Federico Diez ... Matthias Mann
    Parkinson's kinase LRRK2 phosphorylates a distinct subset of Rabs, and LRRK2-dependent phosphorylation links LRKK2 to ciliogenesis.

    Cocaine-induced adaptation of dopamine D2S, but not D2L autoreceptors

    Brooks G Robinson, Alec F Condon ... Kim A Neve
    Desensitization of the D2 autoreceptor is reduced following in vivo cocaine exposure due to plasticity in the D2S and not the D2L splice variant.

    Conserved neural circuit structure across Drosophila larval development revealed by comparative connectomics

    Stephan Gerhard, Ingrid Andrade ... Casey M Schneider-Mizell
    The connectivity structure of a nociceptive circuit is precisely maintained over Drosophila larval development through cell type-specific increases in synaptic contacts as measured from electron microscopy reconstructions, while individual neurons grow five-fold in size and number of synapses.
    1. Neuroscience

    Small conductance Ca2+-activated K+ channels induce the firing pause periods during the activation of Drosophila nociceptive neurons

    Koun Onodera, Shumpei Baba ... Tadao Usui
    Drosophila nociceptive neurons convert high-intensity stimuli into characteristic fluctuations of firing rates, quiescent periods of which are regulated by hyperpolarization through small conductance Ca2+-activated K+ channels.
    1. Neuroscience

    Astrocytes release prostaglandin E2 to modify respiratory network activity

    David Forsberg, Thomas Ringstedt, Eric Herlenius
    Astrocytes modulate neuronal networks during hypercapnia, introducing a novel gliotransmitter pathway where prostaglandin E2 regulates breathing.
    1. Neuroscience

    Causal evidence for lateral prefrontal cortex dynamics supporting cognitive control

    Derek Evan Nee, Mark D'Esposito
    Non-invasive brain stimulation tests and refines a model of lateral prefrontal cortex neural dynamics supporting cognitive control.
    1. Neuroscience

    Signal integration at spherical bushy cells enhances representation of temporal structure but limits its range

    Christian Keine, Rudolf Rübsamen, Bernhard Englitz
    Inhibition reduces the neuronal representation of acoustic signals to enhance temporal precision in the auditory brainstem.
    1. Neuroscience

    Preconditioned cues have no value

    Melissa J Sharpe, Hannah M Batchelor, Geoffrey Schoenbaum
    Preconditioned cues provide information about an associative model but do not, by default, trigger representations of value, either model-based or model-free.
