    Bumblebee visual allometry results in locally improved resolution and globally improved sensitivity

    Gavin J Taylor et al.
    1. Neuroscience

    Individual differences in selective attention predict speech identification at a cocktail party

    Daniel Oberfeld, Felicitas Klöckner-Nowotny
    Cocktail-party listening performance in normal-hearing listeners is associated with the ability to focus attention on a target stimulus in the presence of distractors.
    1. Evolutionary Biology

    The genetic architecture of gene expression levels in wild baboons

    Jenny Tung et al.
    RNA sequencing of individuals within a wild baboon population reveals extensive power to detect functional regulatory variation, and suggests that the set of genes affected by such variation may be conserved across species.

    2. Neuroscience

    Fundamental bound on the persistence and capacity of short-term memory stored as graded persistent activity

    Onur Ozan Koyluoglu et al.
    A fundamental lower-bound on memory recall precision, which declines with storage duration and number of stored items, is derived, and human performance is shown to be well-fit by this theoretical bound.
    1. Neuroscience

    Attenuation of dopamine-modulated prefrontal value signals underlies probabilistic reward learning deficits in old age

    Lieke de Boer et al.
    Attenuated anticipatory activity in ventromedial prefrontal cortex is modulated by dopamine D1 receptor density in nucleus accumbens, and accounts for impaired probabilistic reward learning in older adults.

    2. Genetics and Genomics

    Extensive intraspecies cryptic variation in an ancient embryonic gene regulatory network

    Yamila N Torres Cleuren et al.
    Quantitative genetic analyses reveal remarkably broad genetic variation underlies the requirement for two critical regulatory inputs into a core embryonic gene regulatory network within one animal species.
    1. Neuroscience

    Skill learning strengthens cortical representations of motor sequences

    Tobias Wiestler, Jörn Diedrichsen
    1. Chromosomes and Gene Expression

    Dosage compensation can buffer copy-number variation in wild yeast

    James Hose et al.
    Dosage-compensated gene expression facilitates chromosomal aneuploidy, which presents a rapid route to phenotypic evolution in natural yeast isolates.
