    Reward-based training of recurrent neural networks for cognitive and value-based tasks

    H Francis Song et al.
    A two-part neural network models reward-based training and provides a unified framework in which to study diverse computations that can be compared to electrophysiological recordings from behaving animals.

    GLO-Roots: an imaging platform enabling multidimensional characterization of soil-grown root systems

    Rubén Rellán-Álvarez et al.
    A luminescence-based imaging system is presented that allows soil-based environmental stimuli to be studied in root systems under physiologically relevant conditions.

    Spatially displaced excitation contributes to the encoding of interrupted motion by a retinal direction-selective circuit

    Jennifer Ding et al.
    The direction-selective circuit in the retina adjusts the contributions of excitatory and inhibitory mechanisms under different stimulus conditions to generate context-dependent neural representations of visual features.

    The role of premature evidence accumulation in making difficult perceptual decisions under temporal uncertainty

    Ciara A Devine et al.
    Temporal uncertainty interferes with the timely onset of evidence accumulation in perceptual decision making prompting the brain to rely instead on statistical regularities in the temporal structure of the environment.

    Geometry of antiparallel microtubule bundles regulates relative sliding and stalling by PRC1 and Kif4A

    Sithara Wijeratne, Radhika Subramanian
    Geometrical features of microtubule arrays regulate the collective activity of motor and non-motor proteins.

    Noise modulation in retinoic acid signaling sharpens segmental boundaries of gene expression in the embryonic zebrafish hindbrain

    Julian Sosnik et al.
    Direct measurements of retinoic acid using fluorescence lifetime imaging reveal a new role for cellular retinoic acid binding proteins in noise attenuation that is critical to sharpen hindbrain rhombomere boundaries.

    Dynamics and heterogeneity of a fate determinant during transition towards cell differentiation

    Nicolás Peláez et al.
    The maturation of multi-potent immature cells in the larval eye in Drosophila is regulated by a transcription factor that displays unexpected heterogeneous dynamics during the cells’ transitions towards differentiated states.

    Buffered Qualitative Stability explains the robustness and evolvability of transcriptional networks

    Luca Albergante et al.
    The theory of Buffered Qualitative Stability uses the importance of biological robustness to explain many features of gene regulatory networks in a wide range of organisms, and has implications for diverse biological phenomena including the ability of bacteria and cancer cells to ‘loosen’ their robustness and hence evade treatment.

    Structural characterization of NrnC identifies unifying features of dinucleotidases

    Justin D Lormand et al.
    Dinucleotidases, specialized enzymes that catalyze the final step in RNA degradation, have evolved independently and repeatedly to fulfill essential roles in cell growth.

    Topographic gradients of intrinsic dynamics across neocortex

    Golia Shafiei et al.
    Intrinsic dynamics are shaped by the intersection of molecular, microstructural, connectomic, and activation gradients.
