    Training deep neural density estimators to identify mechanistic models of neural dynamics

    Pedro J Gonçalves et al.
    Deep neural networks can be trained to automatically find mechanistic models which quantitatively agree with experimental data, providing new opportunities for building and visualizing interpretable models of neural dynamics.

    Light-regulated allosteric switch enables temporal and subcellular control of enzyme activity

    Mark Shaaya et al.
    Light-sensitive allosteric switch module, a broadly applicable protein engineering method, is used for the regulation of protein activity with tight temporal control and spatial precision.

    Rapid purification and metabolomic profiling of synaptic vesicles from mammalian brain

    Lynne Chantranupong et al.
    Extensive mass spectrometry-based profiling of polar metabolites within synaptic vesicles that are rapidly isolated either from cultured mouse neurons or directly from mouse brains reveals their neurotransmitter composition.

    Optogenetic inhibition-mediated activity-dependent modification of CA1 pyramidal-interneuron connections during behavior

    Igor Gridchyn et al.
    The optogenetic manipulation of hippocampal neuronal circuit activity revealed plastic changes of pyramidal-interneuron connections in behaving animals, which were primarily governed by the firing rate change of postsynaptic interneurons.

    Neuronal octopamine signaling regulates mating-induced germline stem cell increase in female Drosophila melanogaster

    Yuto Yoshinari et al.
    Genetic analyses using the fruit fly illustrate how neuronal system couples germline stem cell increase to an external cue, which is mating, through stem cell niche signaling.

    Optical control of ERK and AKT signaling promotes axon regeneration and functional recovery of PNS and CNS in Drosophila

    Qin Wang et al.
    Precise spatiotemporal optogenetic activation of ERK and AKT signaling pathways reveals neural repair mechanisms of the peripheral and central nervous systems in live Drosophila larvae.

    A dual role for Cav1.4 Ca2+ channels in the molecular and structural organization of the rod photoreceptor synapse

    J Wesley Maddox et al.
    Ca2+ influx through Cav1.4 channels is required for the structural, but not the molecular organization of the rod photoreceptor synapse.

    The dynamic interplay between ATP/ADP levels and autophagy sustain neuronal migration in vivo

    Cedric Bressan et al.
    Imaging of energy status and autophagy during neuronal migration revealed that ATP/ADP levels dynamically change during the migratory and stationary phases and that ATP reduction induces autophagy to maintain migration.

    Structural insights into human acid-sensing ion channel 1a inhibition by snake toxin mambalgin1

    Demeng Sun et al.
    Mambalgin1 binds to the thumb domain of human ASIC1a channel and inhibits the channel through hindering the proton-induced transitions from the resting closed state to the active and/or desensitized state.

    Antinociceptive modulation by the adhesion GPCR CIRL promotes mechanosensory signal discrimination

    Sven Dannhäuser et al.
    An interdisciplinary approach uncovers a new antinociceptive molecular mechanism and shows that the adhesion GPCR CIRL adjusts the sensation of gentle touch and noxious mechanical insult in opposite directions.
