    Left-right side-specific endocrine signaling complements neural pathways to mediate acute asymmetric effects of brain injury

    Nikolay Lukoyanov et al.
    In addition to the well-established involvement of descending neural tracts, the left-right side-specific endocrine mechanism may contribute to signaling from injured brain to spinal motor circuits.

    Connectional asymmetry of the inferior parietal lobule shapes hemispheric specialization in humans, chimpanzees, and rhesus macaques

    Luqi Cheng et al.
    Humans showed the most widespread asymmetric connectivity between the inferior parietal lobule subregions and the rest of the brain compared to macaques and chimpanzees, which shapes hemispheric specialization in primates.

    The CNS connectome of a tadpole larva of Ciona intestinalis (L.) highlights sidedness in the brain of a chordate sibling

    Kerrianne Ryan et al.
    Serial-section EM analysis uncovers the CNS connectome of a Ciona larva, the second of any entire nervous system, and exposes left-right asymmetries in its synaptic circuits.

    Acyl chain asymmetry and polyunsaturation of brain phospholipids facilitate membrane vesiculation without leakage

    Marco M Manni et al.
    The asymmetric combination of saturated and polyunsaturated acyl chains in phospholipids as typically observed in synapses makes membranes prone to deformation and fission without compromising their impermeability.

    Grid-cell representations in mental simulation

    Jacob LS Bellmund et al.
    Functional magnetic resonance imaging performed while people imagined directions from stationary viewpoints supports theories suggesting that spatially tuned cells such as grid cells underlie mental simulation for future thinking.

    Regulation of branching dynamics by axon-intrinsic asymmetries in Tyrosine Kinase Receptor signaling

    Marlen Zschätzsch et al.
    Asymmetric localization of the receptor EGFR within branches of axons is required to establish the precise wiring of neuronal networks within the Drosophila brain.

    Asymmetric neurogenic commitment of retinal progenitors involves Notch through the endocytic pathway

    Elisa Nerli et al.
    A quantitative live imaging approach unveils that earliest neurogenic progenitors in the vertebrate retina arise from asymmetric divisions and that this asymmetry involves Notch signalling through the endocytic pathway.

    Synaptic learning rules for sequence learning

    Eric Torsten Reifenstein et al.
    Through mathematical analysis and computer simulations, the neuronal underpinnings of feasible models of sequence learning are delineated.

    Chimpanzee brain morphometry utilizing standardized MRI preprocessing and macroanatomical annotations

    Sam Vickery et al.
    Openly available structural imaging processing pipeline for chimpanzees including registration templates and macro-anatomical parcellation shows human-like cerebral aging and medial hemispheric organization.

    Typical and atypical language brain organization based on intrinsic connectivity and multitask functional asymmetries

    Loïc Labache et al.
    Left-hander's atypical language brain organization, revealed by task-induced rightward asymmetry, is underpinned at rest by homotopic networks wired for language bilaterally and strong intrinsic connectivity through a large corpus callosum.
