    Determining the scale at which variation in a single gene changes population yields

    Erica McGale, Henrique Valim ... Ian T Baldwin
    Variation in the gene NaMPK4 in plant populations increases reproductive yield, an effect which appears to be independent of soil water availability, neighbor-scale interactions and associations with arbuscular mycorrhizal fungi.

    Inferring synaptic inputs from spikes with a conductance-based neural encoding model

    Kenneth W Latimer, Fred Rieke, Jonathan W Pillow
    The conductance-based encoding model creates a new bridge between statistical models and biophysical models of neurons, and infers visually-evoked excitatory and inhibitory synaptic conductances from spike trains in macaque retina.
    1. Neuroscience

    Subpopulations of neurons in lOFC encode previous and current rewards at time of choice

    David L Hocker, Carlos D Brody ... Christine M Constantinople
    A distinct subpopulation of neurons in the rat orbitofrontal cortex encodes reward history at the time of choice, providing a potential neural substrate by which reward history may influence decisions.
    1. Neuroscience

    A statistical framework to assess cross-frequency coupling while accounting for confounding analysis effects

    Jessica K Nadalin, Louis-Emmanuel Martinet ... Mark A Kramer
    A new measure for cross-frequency coupling assesses phase-amplitude coupling and amplitude-amplitude coupling, and accounts for confounding factors such as low-frequency amplitude fluctuations, using a flexible statistical modeling approach.

    Stochastic logistic models reproduce experimental time series of microbial communities

    Lana Descheemaeker, Sophie de Buyl
    Properties of various microbial communities time series, such as the noise color and neutrality, are captured by stochastic generalized Lotka-Volterra equations, even in the absence of interactions.

    Cisplatin-induced DNA double-strand breaks promote meiotic chromosome synapsis in PRDM9-controlled mouse hybrid sterility

    Liu Wang, Barbora Valiskova, Jiri Forejt
    The exogenous DNA DSBs improve meiotic chromosome pairing in mouse inter-subspecific hybrids, thus providing an evidence for a DSB-dependent mechanism of the PRDM9-controlled synapsis failure and infertility.
    1. Neuroscience

    Stimulus-dependent relationships between behavioral choice and sensory neural responses

    Daniel Chicharro, Stefano Panzeri, Ralf M Haefner
    New stimulus-dependencies of choice-related signals in sensory neurons uncovered by new analytical results and methods.

    Prediction of primary somatosensory neuron activity during active tactile exploration

    Dario Campagner, Mathew Hywel Evans ... Rasmus Strange Petersen
    Primary trigeminal neurons encode rotational forces in awake mice as they explore an object with their whiskers, allowing accurate prediction of spiking during behaviour.

    Plant defense phenotypes determine the consequences of volatile emission for individuals and neighbors

    Meredith C Schuman, Silke Allmann, Ian T Baldwin
    Both the frequency of sesquiterpene-emitting individuals and the defense capacity of individual plants determine the consequences of sesquiterpene volatile emission for individuals and their neighbors in populations of the wild tobacco Nicotiana attenuata.

    Decoupling kinematics and mechanics reveals coding properties of trigeminal ganglion neurons in the rat vibrissal system

    Nicholas E Bush, Christopher L Schroeder ... Mitra JZ Hartmann
    Primary sensory neurons of the rat whisker system encode contact with objects in terms of the forces exerted on whiskers, rather than the induced whisker movements.
