    Simultaneous activation of parallel sensory pathways promotes a grooming sequence in Drosophila

    Stefanie Hampel, Claire E McKellar ... Andrew M Seeds
    A grooming sequence is produced by a neural architecture that readies different movements simultaneously, and a mechanism where prioritized suppression between the movements determines their sequential performance.

    A suppression hierarchy among competing motor programs drives sequential grooming in Drosophila

    Andrew M Seeds, Primoz Ravbar ... Julie H Simpson
    Gaining genetic control over neural modules that drive the grooming of each Drosophila body part reveals how mechanisms for selecting among competing behavioral choices are used to generate sequences of actions.

    Corticofugal regulation of predictive coding

    Alexandria MH Lesicko, Christopher F Angeloni ... Maria N Geffen
    A specific neuronal pathway within the auditory system represents information about the statistical prediction and error for incoming sounds, thereby contributing to efficient representation of complex sounds and sound streams in the brain.

    Arid1a restrains Kras-dependent changes in acinar cell identity

    Geulah Livshits, Direna Alonso-Curbelo ... Scott W Lowe
    Arid1a loss in the pancreas enables an irreversible reprogramming of cell fate that is dependent on both cellular and genetic context.

    Breaking down hierarchies of decision-making in primates

    Alexandre Hyafil, Rubén Moreno-Bote
    Computational modeling of behavioral and neural data from monkeys points towards a flat decision-making process in which the brain considers all possible final outcomes simultaneously.

    Loss of the multifunctional RNA-binding protein RBM47 as a source of selectable metastatic traits in breast cancer

    Sakari Vanharanta, Christina B Marney ... Joan Massagué
    Inactivation of a multifunctional RNA-binding protein can lead to the acquisition of pro-metastatic phenotypes, possibly by stabilizing large-scale transcriptomic changes that provide a selective advantage during cancer progression.

    Binocular rivalry reveals an out-of-equilibrium neural dynamics suited for decision-making

    Robin Cao, Alexander Pastukhov ... Jochen Braun
    The statistics of binocular rivalry at different combinations of image contrast is reproduced quantitatively by competing out-of-equilibrium populations of independent neural assemblies with idealized attractor dynamics.

    Prediction error and repetition suppression have distinct effects on neural representations of visual information

    Matthew F Tang, Cooper A Smout ... Jason B Mattingley
    Multivariate analyses of human electrophysiological recordings revealed that the brain represents unexpected visual stimuli with greater fidelity than expected stimuli which arose independently of simple habituation arising from repetition.

    The neuropeptide F/nitric oxide pathway is essential for shaping locomotor plasticity underlying locust phase transition

    Li Hou, Pengcheng Yang ... Le Kang
    Two neuropeptides, NPF1a and NPF2, act via the nitric oxide signaling pathway in the locust brain to regulate the trait transition between solitary and swarming behavior.

    Nested circuits mediate the decision to vocalize

    Shuyun Xiao, Valerie Michael, Richard Mooney
    The decision to vocalize depends on neural circuits that balance the rewards of potential social affiliation with the risks of advertising.
