    Synaptic proteins promote calcium-triggered fast transition from point contact to full fusion

    Jiajie Diao, Patricia Grob ... Axel T Brunger
    A combination of advanced optical imaging and cryogenic electron microscopy has been used to explore membrane fusion in a synthetic system and provide new insights into neurotransmitter release.

    Structural analyses at pseudo atomic resolution of Chikungunya virus and antibodies show mechanisms of neutralization

    Siyang Sun, Ye Xiang ... Michael G Rossmann
    Electron cryo-microscopy has been used to determine the structure of Chikungunya virus-like particles and to provide new insights into their interactions with four different antibodies.

    Controlling gain one photon at a time

    Gregory W Schwartz, Fred Rieke
    Single absorbed photons trigger adaptational mechanisms that help the retina maintain sensitivity across a wide range of background illumination.
    1. Neuroscience

    Cell type-specific and time-dependent light exposure contribute to silencing in neurons expressing Channelrhodopsin-2

    Alexander M Herman, Longwen Huang ... Benjamin R Arenkiel
    Optogenetic techniques, whereby light is used to activate neuronal cells, are quickly becoming widely used in neuroscience; but excessive exposure to light can actually silence certain types of neuronal cells.

    RGS7/Gβ5/R7BP complex regulates synaptic plasticity and memory by modulating hippocampal GABABR-GIRK signaling

    Olga Ostrovskaya, Keqiang Xie ... Kirill A Martemyanov
    A critical regulator of inhibitory neurotransmitter signaling in the hippocampus has been identified in experiments on mice and been shown to play essential role in synaptic plasticity and memory.

    The inhibitory microcircuit of the substantia nigra provides feedback gain control of the basal ganglia output

    Jennifer Brown, Wei-Xing Pan, Joshua Tate Dudman
    Negative feedback signals within the substantia nigra regulate the output of the basal ganglia, with implications for disorders such as Parkinson's disease.

    Enhancement of encoding and retrieval functions through theta phase-specific manipulation of hippocampus

    Joshua H Siegle, Matthew A Wilson
    The ability of mice to encode new memories or retrieve existing ones can be selectively manipulated by using optogenetics to inhibit hippocampal activity at specific phases of the theta cycle.

    A role for descending auditory cortical projections in songbird vocal learning

    Yael Mandelblat-Cerf, Liora Las ... Michale S Fee
    Midbrain dopaminergic neurons and a cortex-like structure called the arcopallium form part of a circuit that enables young songbirds to compare their own song with a template stored in memory, and use any discrepancies to improve their performance.

    Laser ablation of Dbx1 neurons in the pre-Bötzinger complex stops inspiratory rhythm and impairs output in neonatal mice

    Xueying Wang, John A Hayes ... Christopher A Del Negro
    Laser-ablating neurons of a single genetic class reveals that Dbx1-derived interneurons comprise core respiratory rhythmogenic and premotor circuits and provides quantitative cellular parameters that govern network functionality

    Coding of stimulus strength via analog calcium signals in Purkinje cell dendrites of awake mice

    Farzaneh Najafi, Andrea Giovannucci ... Javier F Medina
    Sensory-driven calcium spikes in Purkinje cells are not binary; instead, they are graded and can provide information about the strength of a periocular airpuff stimulus known to drive learning.
