    Broca's cerebral asymmetry reflects gestural communication's lateralisation in monkeys (Papio anubis)

    Yannick Becker, Nicolas Claidière ... Adrien Meguerditchian
    A brain MRI imaging study on brain and manual lateralisation in 50 baboons shows that communicative manual gesturing is related to a Broca's area marker.

    What happens to the inhibitory control functions of the right inferior frontal cortex when this area is dominant for language?

    Esteban Villar-Rodríguez, Cristina Cano-Melle ... César Avila
    A complementary relationship exists between the hemispheric lateralization of inhibitory control (typically right) and speech (typically left), as observed in typically and atypically lateralized left-handed individuals.

    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.

    Temporo-cerebellar connectivity underlies timing constraints in audition

    Anika Stockert, Michael Schwartze ... Sonja A Kotz
    With unique lesion-informed tractography, left hemisphere temporo-cerebellar structural connectivity has been established, supporting rapid auditory transmission and cortical functional lateralization.

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

    Loïc Labache, Bernard Mazoyer ... Nathalie Tzourio-Mazoyer
    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.

    State-dependent geometry of population activity in rat auditory cortex

    Dmitry Kobak, Jose L Pardo-Vazquez ... Alfonso Renart
    Representation of sound lateralisation and intensity by neural population in the rat auditory cortex strongly depends on the brain state suggesting that the neural tuning to lateralisation is not hard-wired.

    Distinct roles of forward and backward alpha-band waves in spatial visual attention

    Andrea Alamia, Lucie Terral ... Rufin VanRullen
    Covert visual attention modulates alpha-band traveling waves propagating from frontal to occipital regions in both hemispheres, yet it modulates waves propagating in the opposite direction (occipital to frontal) only in the presence of visual stimulation.

    Manganese-enhanced magnetic resonance imaging reveals light-induced brain asymmetry in embryo

    Elena Lorenzi, Stefano Tambalo ... Angelo Bifone
    The protocol reported can open the way to investigation of the effects of a variety of sensory stimulations on brain activity in embryo.

    Population rate-coding predicts correctly that human sound localization depends on sound intensity

    Antje Ihlefeld, Nima Alamatsaz, Robert M Shapley
    Softer sound appears closer to midline than louder sound, conflicting with a labelled-line representation of auditory space and supporting the idea that humans use rate coding when calculating sound directionality.
    1. Neuroscience

    Functional specialization within the inferior parietal lobes across cognitive domains

    Ole Numssen, Danilo Bzdok, Gesa Hartwigsen
    Data-driven and effective connectivity analyses reveal patterns of functional specialization, common mechanisms, and brain-wide interaction profiles within the human inferior parietal lobes for multiple functional domains.
