    Functional fission of parvalbumin interneuron classes during fast network events

    Csaba Varga et al.
    There is surprising functional splitting of major hippocampal GABA cell classes during high-frequency network oscillations that doubles the repertoire of spatio-temporal patterns of GABA release.

    Diverse modes of synaptic signaling, regulation, and plasticity distinguish two classes of C. elegans glutamatergic neurons

    Donovan Ventimiglia, Cornelia I Bargmann
    Single-neuron synaptic imaging in vivo demonstrates that highly conserved molecules such as UNC-13, UNC-18, and protein kinase C, which are found at essentially every synapse make different functional contributions in Caenorhabditis elegans glutamatergic neurons.
    1. Cell Biology

    The fibronectin synergy site re-enforces cell adhesion and mediates a crosstalk between integrin classes

    Maria Benito-Jardón et al.
    The fibronectin synergy site is only required in vivo when forces exceed or αvβ3 integrin levels fall below certain thresholds.

    Stapled Golgi cisternae remain in place as cargo passes through the stack

    Gregory Lavieu et al.
    The cisternae of the Golgi contain two functionally distinct domains: the central areas, which remain stationary, and the edges or rims, which are mobile.

    A florigen paralog is required for short-day vernalization in a pooid grass

    Daniel Woods et al.
    In Brachypodiumdistachyon, a single locus accounts for natural variation in whether perception of short day-lengths confers competence to flower.
    1. Ecology

    Strong biomechanical relationships bias the tempo and mode of morphological evolution

    Martha M Muñoz et al.
    The rules of biomechanics consistently influence the tempo (rate) and mode (pattern) of evolution across four-bar linkage systems in animals.
    1. Neuroscience

    A predictive focus of gain modulation encodes target trajectories in insect vision

    Steven D Wiederman et al.
    Visual neurons in the dragonfly predict the path of a moving target, even when it is occluded or crosses from one eye to the other.
    1. Neuroscience

    Integrated action of pheromone signals in promoting courtship behavior in male mice

    Sachiko Haga-Yamanaka et al.
    Identification of two classes of mouse vomeronasal receptors for female pheromone cues suggests distinct gating mechanisms in pheromone-triggered reproductive behaviors.
    1. Ecology

    Mass enhances speed but diminishes turn capacity in terrestrial pursuit predators

    Rory P Wilson et al.
    Increased mass enhances speed but compromises turning capacity in pursuit predators; this has widespread ramifications for the best strategies for predators and prey during chases according to their relative masses.
    1. Neuroscience

    A genetically defined asymmetry underlies the inhibitory control of flexor–extensor locomotor movements

    Olivier Britz et al.
    Two classes of premotor inhibitory neurons have specific roles in controlling flexor-extensor behaviors in mice, which is the underlying neural mechanism for limb driven movements in terrestrial vertebrates.
