    Representational untangling by the firing rate nonlinearity in V1 simple cells

    Merse E Gáspár, Pierre-Olivier Polack ... Gergő Orbán
    Firing rate nonlinearity recovers linear decodability of orientation information from simple cells of the primary visual cortex under uncertainty of nuisance parameters phase and spatial frequency.

    The paraventricular thalamus is a critical mediator of top-down control of cue-motivated behavior in rats

    Paolo Campus, Ignacio R Covelo ... Shelly B Flagel
    A top-down circuit generating from the prelimbic cortex and projecting to the paraventricular nucleus of the thalamus mediates individual differences in cue-elicited responding by affecting subcortical dopamine-dependent incentive learning.

    Seminal fluid compromises visual perception in honeybee queens reducing their survival during additional mating flights

    Joanito Liberti, Julia Görner ... Boris Baer
    After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.

    Processing of different spatial scales in the human brain

    Michael Peer, Yorai Ron ... Shahar Arzy
    When subjects perform spatial judgments in environments of increasing scale, brain activity shifts along posterior-anterior gradients, advancing from the visual system to the default-mode network.

    Humans can efficiently look for but not select multiple visual objects

    Eduard Ort, Johannes Jacobus Fahrenfort ... Christian NL Olivers
    During search for multiple targets, individuals can efficiently prepare to select multiple target objects simultaneously, but the actual selection of those objects from the sensory input is limited.

    Adaptive substitutions underlying cardiac glycoside insensitivity in insects exhibit epistasis in vivo

    Andrew M Taverner, Lu Yang ... Peter Andolfatto
    Genome engineering and phenotyping in vivo reveal surprising new features of adaptive amino acid substitutions that were previously inaccessible.

    Notch signalling maintains Hedgehog responsiveness via a Gli-dependent mechanism during spinal cord patterning in zebrafish

    Craig T Jacobs, Peng Huang
    Genetic analyses combining photoconvertible cell signalling reporters with gain- and loss-of function manipulations reveal a novel role for Notch signalling in controlling Hedgehog response in neural progenitor cells.

    A genetic selection reveals functional metastable structures embedded in a toxin-encoding mRNA

    Sara Masachis, Nicolas J Tourasse ... Fabien Darfeuille
    A genetic selection of toxicity suppressors coupled to high-throughput sequencing has captured metastable RNA structures that co-transcriptionally inhibit the translation of a bacterial toxin.

    Molecular basis for dyneinopathies reveals insight into dynein regulation and dysfunction

    Matthew G Marzo, Jacqueline M Griswold ... Steven M Markus
    A mutagenesis screen in budding yeast sheds light on dynein regulation and function, and reveals the molecular basis for disease in patients suffering from neuropathies caused by dynein dysfunction.

    Apicomplexan-like parasites are polyphyletic and widely but selectively dependent on cryptic plastid organelles

    Jan Janouškovec, Gita G Paskerova ... Timur G Simdyanov
    Apicomplexan-like parasites originated several times independently and many of them contain cryptic plastid organelles, which demonstrate that the parasites evolved from photosynthetic algae.
