    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.

    Gating of reafference in the external cuneate nucleus during self-generated movements in wake but not sleep

    Alexandre Tiriac, Mark S Blumberg
    A neural gating mechanism in the external cuneate nucleus of the rat brain is engaged during wake movements and disengaged during sleep-related twitches.

    Cortico-subcortical β burst dynamics underlying movement cancellation in humans

    Darcy A Diesburg, Jeremy DW Greenlee, Jan R Wessel
    Burst-like neural activity in the β-frequency band conveys inhibitory commands within long-proposed cortico-subcortical networks for motor inhibition, with inhibitory activity in STN preceding thalamic activity, which has strong implications for movement disorders marked by abnormalities in β-bursting.

    Accelerated redevelopment of vocal skills is preceded by lasting reorganization of the song motor circuitry

    Michiel Vellema, Mariana Diales Rocha ... Manfred Gahr
    The ability to quickly re-acquire a previously lost motor skill is associated with lasting synaptic changes in the brain circuit that controls that motor skill.

    Right inferior frontal gyrus implements motor inhibitory control via beta-band oscillations in humans

    Michael Schaum, Edoardo Pinzuti ... Oliver Tüscher
    Response inhibition is initiated by the right inferior frontal gyrus (rIFG), and stopping performance is predicted by beta-band power as well as beta-band connectivity between rIFG and pre-supplementary motor area.

    Right inferior frontal gyrus damage is associated with impaired initiation of inhibitory control, but not its implementation

    Yoojeong Choo, Dora Matzke ... Jan R Wessel
    Hierarchical Bayesian modeling of stop-signal task performance in humans with and without lesions to the right inferior gyrus reveals that rather than implementing inhibitory control, this brain region appears to be responsible for detecting the need to inhibit an action.

    Induced sensorimotor cortex plasticity remediates chronic treatment-resistant visual neglect

    Jacinta O'Shea, Patrice Revol ... Yves Rossetti
    Tonic disinhibition of left motor cortex during prism adaptation enhanced consolidation of sensorimotor and cognitive prism after effects, causing lasting clinical gains in three patient cases with chronic treatment-resistant visual neglect.

    Removal of inhibition uncovers latent movement potential during preparation

    Uday K Jagadisan, Neeraj J Gandhi
    Non-invasive disinhibition of the oculomotor system shows that ongoing preparatory activity in the superior colliculus has movement-generating potential and need not rise to threshold in order to produce a saccade.
    1. Neuroscience

    A hierarchy of timescales explains distinct effects of local inhibition of primary visual cortex and frontal eye fields

    Luca Cocchi, Martin V Sale ... Jason B Mattingley
    The selective effect of local inhibition on diffuse patterns of brain connectivity can be accounted for by an intrinsic hierarchical ordering of cortical timescales.
    1. Neuroscience

    New learning while consolidating memory during sleep is actively blocked by a protein synthesis dependent process

    Roi Levy, David Levitan, Abraham J Susswein
    The brain inhibits the formation of new memories just after waking to safeguard the ongoing stabilization of existing memories during sleep.
