    Motor cortex signals for each arm are mixed across hemispheres and neurons yet partitioned within the population response

    Katherine Cora Ames, Mark M Churchland
    Neurons in motor cortex contain information about each arm, but these signals are separated into different dimensions, allowing separate control of each arm.

    Spatial modulation of visual responses arises in cortex with active navigation

    E Mika Diamanti et al.
    Spatial modulation along the visual pathway arises in the cortex and strengthens with active navigation and experience.

    Population response magnitude variation in inferotemporal cortex predicts image memorability

    Andrew Jaegle et al.
    Population response magnitude predicts how well an image will be remembered, in both monkey inferotemporal cortex and neural networks trained to categorize objects.

    Mouse V1 population correlates of visual detection rely on heterogeneity within neuronal response patterns

    Jorrit S Montijn et al.
    Heterogeneity of neural responses in mouse cortex correlates better with visual detection than mean population activity.

    Paradoxical response reversal of top-down modulation in cortical circuits with three interneuron types

    Luis Carlos Garcia del Molino et al.
    Computational simulations and mathematical derivations reveal why the response of neural populations to external modulation is sometimes reversed with respect to what intuition would lead to believe in cortical circuits with multiple types of inhibitory neurons.

    The evolution of distributed sensing and collective computation in animal populations

    Andrew M Hein et al.
    A computational model shows that natural selection can cause populations to evolve a distinctive population-level phenotype: the ability to transition between collective states in response to the environment.

    Population coupling predicts the plasticity of stimulus responses in cortical circuits

    Yann Sweeney, Claudia Clopath
    Networks simulations and in vivo imaging suggest a stable backbone of stimulus representation formed by neurons with low population coupling, alongside a flexible substrate of neurons with high population coupling.

    Endocannabinoid signaling enhances visual responses through modulation of intracellular chloride levels in retinal ganglion cells

    Loïs S Miraucourt et al.
    Endocannabinoid activation of the CB1 receptor on retinal ganglion cells in the eye results in enhanced excitability and responsiveness to visual stimulation through a novel mechanism involving intracellular chloride regulation.

    Selection of distinct populations of dentate granule cells in response to inputs as a mechanism for pattern separation in mice

    Wei Deng et al.
    By using different groups of cells to represent distinct environments and events, the dentate gyrus of the hippocampus helps to keep memories of similar events separate.

    Tissue-specific modulation of gene expression in response to lowered insulin signalling in Drosophila

    Luke Stephen Tain et al.
    Multi-omic profiling of gene expression in response to reduced insulin/IGF-like-signalling reveals tissue-specific regulation of DNA damage and lysosomal mannosidase regulation of tissue homeostasis as pro-longevity responses.
