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

    Luqi Cheng, Yuanchao Zhang ... Tianzi Jiang
    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.

    Modulation of alpha oscillations by attention is predicted by hemispheric asymmetry of subcortical regions

    Tara Ghafari, Cecilia Mazzetti ... Ole Jensen
    Lateral asymmetry of the globus pallidus, caudate nucleus, and thalamus can predict attention-related modulations of posterior alpha oscillations when combining structural MRI with MEG.

    Heritability and cross-species comparisons of human cortical functional organization asymmetry

    Bin Wan, Şeyma Bayrak ... Sofie L Valk
    Human brain suggests an asymmetric organization along a functional cortical axis describing a hierarchical functional trajectory from perceptual/action to abstract cognition, which is heritable and comparable with macaque brain, suggesting (phylo)genetic conservation and adaptation.

    Microstructural asymmetries of the planum temporale predict functional lateralization of auditory-language processing

    Peipei Qin, Qiuhui Bi ... Gaolang Gong
    The important role of structural asymmetry in the functional lateralization of the same brain area provides a crucial insight into the neurobiological fundament for human brain's functional lateralization.

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

    Nikolay Lukoyanov, Hiroyuki Watanabe ... Georgy Bakalkin
    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.

    Left hemisphere dominance for bilateral kinematic encoding in the human brain

    Christina M Merrick, Tanner C Dixon ... Richard B Ivry
    An electrode-wise encoding model based on physiological recordings from the cortical surface revealed a striking hemispheric asymmetry where the encoding of ipsilateral movement was stronger in the left hemisphere compared to the right hemisphere.

    Normalisation of brain connectivity through compensatory behaviour, despite congenital hand absence

    Avital Hahamy, Stamatios N Sotiropoulos ... Tamar R Makin
    Building on previous work (Makin et al., 2013), we show that the brains of individuals born without a hand adaptively change to compensate for their disability.

    Chimpanzee brain morphometry utilizing standardized MRI preprocessing and macroanatomical annotations

    Sam Vickery, William D Hopkins ... Felix Hoffstaedter
    Openly available structural imaging processing pipeline for chimpanzees including registration templates and macro-anatomical parcellation shows human-like cerebral aging and medial hemispheric organization.

    Tracing the development and lifespan change of population-level structural asymmetry in the cerebral cortex

    James M Roe, Didac Vidal-Pineiro ... René Westerhausen
    Brain asymmetry in cortical surface area shows lifespan stability from early childhood to old age and is more underpinned by genetic differences, whereas asymmetry in cortical thickness grows through childhood and adolescence and is minimally explained by genetics.

    Epigenetic regulation of lateralized fetal spinal gene expression underlies hemispheric asymmetries

    Sebastian Ocklenburg, Judith Schmitz ... Onur Güntürkün
    Gene expression asymmetries in fetal spinal cord are triggered by epigenetic mechanisms suggesting that handedness has a spinal instead of a cortical origin.
