    Excitatory neurons are more disinhibited than inhibitory neurons by chloride dysregulation in the spinal dorsal horn

    Kwan Yeop Lee et al.
    The flow of somatosensory information through the spinal dorsal horn is regulated by synaptic inhibition, which acts upon excitatory and inhibitory interneurons, but the former are especially prone to disinhibition.

    Neural activity related to volitional regulation of cortical excitability

    Kathy Ruddy et al.
    Changing brain state using feedback from transcranial magnetic stimulation, by training participants to increase or decrease how excitable their motor pathways are.

    Induced sensorimotor cortex plasticity remediates chronic treatment-resistant visual neglect

    Jacinta O'Shea et al.
    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.

    Dopamine neurons projecting to medial shell of the nucleus accumbens drive heroin reinforcement

    Julie Corre et al.
    Disinhibition of dopamine neurons in the midbrain drives heroin reinforcement, the initial step towards opioid addiction.

    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.

    Electrocorticographic dissociation of alpha and beta rhythmic activity in the human sensorimotor system

    Arjen Stolk et al.
    Direct cortical recordings in humans link the spectral structure of local field potentials to inhibition/disinhibition mechanisms coordinating sensorimotor neuronal populations during movement imagery.

    Prefrontal dopamine regulates fear reinstatement through the downregulation of extinction circuits

    Natsuko Hitora-Imamura et al.
    Prefrontal dopamine regulates inhibition of fear extinction circuits in the infralimbic cortex and disinhibition of fear expression circuits in the amygdala, leading to fear reinstatement.

    Lognormal firing rate distribution reveals prominent fluctuation–driven regime in spinal motor networks

    Peter C Petersen, Rune W Berg
    Neuronal participation in generation of motor patterns in the spinal circuits is lognormal, which is an indication of a rich diversity of activity within the mean-driven as well as the fluctuation-driven regimes.

    PIP2 depletion promotes TRPV4 channel activity in mouse brain capillary endothelial cells

    Osama F Harraz et al.
    TRPV4 channels in brain capillaries are suppressed by the phosphoinositide PIP2 and activated by receptor agonists implicated in neurovascular coupling.

    Reciprocal regulation of ARPP-16 by PKA and MAST3 kinases provides a cAMP-regulated switch in protein phosphatase 2A inhibition

    Veronica Musante et al.
    A complex interplay between MAST3 and PKA protein kinases and the regulatory protein ARPP-16 allows cAMP to control the activity of protein phosphatase 2A.
