    Neural precursors of decisions that matter—an ERP study of deliberate and arbitrary choice

    Uri Maoz, Gideon Yaffe ... Liad Mudrik
    The readiness potential—a long-established neural precursor of voluntary action claimed to precede the onset of the conscious decision to move—is absent, or at least significantly reduced, for deliberate decisions.

    Juxtaposition of heterozygous and homozygous regions causes reciprocal crossover remodelling via interference during Arabidopsis meiosis

    Piotr A Ziolkowski, Luke E Berchowitz ... Ian R Henderson
    Heterozygosity changes the balance between interfering and non-interfering crossovers during Arabidopsis meiosis.

    Flexible control of representational dynamics in a disinhibition-based model of decision-making

    Bo Shen, Kenway Louie, Paul Glimcher
    Local disinhibition provides a biologically plausible mechanism for flexible top-down control of network states that integrates normalized value coding, winner-take-all choice, and persistent activity in a single circuit of decision-making.

    Dynamics of ribosomes and release factors during translation termination in E. coli

    Sarah Adio, Heena Sharma ... Marina V Rodnina
    Translation termination is a stochastic process that utilizes loosely coupled motions of its players to complete protein synthesis and release the newly synthesized nascent chain toward its cellular destination.

    Genome-scale annotation of protein binding sites via language model and geometric deep learning

    Qianmu Yuan, Chong Tian, Yuedong Yang
    Integration of language model and geometric deep learning enables accurate and efficient genome-scale annotation of comprehensive protein-ligand binding sites.

    Nucleus accumbens dopamine tracks aversive stimulus duration and prediction but not value or prediction error

    Jessica N Goedhoop, Bastijn JG van den Boom ... Ingo Willuhn
    The extracellular concentration of dopamine in the nucleus accumbens core is progressively diminished by white noise, an underutilized, easy-to-titrate aversive stimulus, but is unaffected by white-noise intensity, context valence, and associated probabilistic contingencies.

    The structure of behavioral variation within a genotype

    Zachary Werkhoven, Alyssa Bravin ... Benjamin L de Bivort
    Multidimensional analysis of data from high-throughput behavioral assays reveals many independent axes of behavioral variation among inbred animals reared in the same environment.

    Olfactory receptor neurons generate multiple response motifs, increasing coding space dimensionality

    Brian Kim, Seth Haney ... Mark A Stopfer
    The odor-elicited responses of olfactory receptor neurons consist of a discrete set of four spike pattern motifs, each with distinct adaptation properties, together amplifying distinctions between similar and temporally complex chemical inputs such as odor plumes.

    Surface color and predictability determine contextual modulation of V1 firing and gamma oscillations

    Alina Peter, Cem Uran ... Martin Vinck
    Colored surfaces induce strong gamma-synchronization yet sparse firing in V1 when receptive field inputs are predicted from the surrounding spatial context.

    Consistent global structures of complex RNA states through multidimensional chemical mapping

    Clarence Yu Cheng, Fang-Chieh Chou ... Rhiju Das
    A multidimensional chemical mapping strategy enables confident determination of the structures of non-coding RNAs at 1-nm resolution, including previously intractable riboswitch and human regulon states.
