    Spatially bivariate EEG-neurofeedback can manipulate interhemispheric inhibition

    Masaaki Hayashi, Kohei Okuyama ... Junichi Ushiba
    Interhemispheric inhibition can be manipulated by directly and bidirectionally modulating the bilateral sensorimotor excitabilities in a spatially bivariate Brain-Computer Interface-based neurofeedback paradigm.

    Combining robotic training and inactivation of the healthy hemisphere restores pre-stroke motor patterns in mice

    Cristina Spalletti, Claudia Alia ... Matteo Caleo
    A combined rehabitative protocol after stroke in the mouse normalizes transcallosal inhibition and promotes "true recovery" of forelimb motor function.

    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.

    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.

    Local GABA concentration is related to network-level resting functional connectivity

    Charlotte J Stagg, Velicia Bachtiar ... Heidi Johansen-Berg
    In the brain at rest, the degree of coordinated activity within the motor network is inversely related to levels of the inhibitory transmitter GABA in primary motor cortex.

    Homotopic contralesional excitation suppresses spontaneous circuit repair and global network reconnections following ischemic stroke

    Annie R Bice, Qingli Xiao ... Adam Q Bauer
    Excitation of contralesional cortex after stroke suppresses the expression of genes related to plastic neuronal reintegration and accordingly modulates perilesional remodeling and functional network communication at local and global scales.
    1. Neuroscience

    Cerebral chemoarchitecture shares organizational traits with brain structure and function

    Benjamin Hänisch, Justine Y Hansen ... Sofie Louise Valk
    Dimensionality reduction techniques reveal how the organization of neurotransmitter receptor and transporter co-expression in the human brain may bridge the gap between brain structure and function.

    Transcranial magnetic stimulation (TMS) inhibits cortical dendrites

    Sean C Murphy, Lucy M Palmer ... Matthew E Larkum
    Studying the activity of cortical neurons in rats reveals the subcellular effects of transcranial magnetic stimulation, which is used for the non-invasive treatment of a variety of brain disorders.

    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.

    Feedback contribution to surface motion perception in the human early visual cortex

    Ingo Marquardt, Peter De Weerd ... Kâmil Uludağ
    Novel evidence for a role of feedback in the perception of uniform surfaces in the human brain suggests that feedback already re-enters at an early visual processing stage.
