    Cell-specific gain modulation by synaptically released zinc in cortical circuits of audition

    Charles T Anderson, Manoj Kumar ... Thanos Tzounopoulos
    Synaptic zinc is a novel modulator of cortical sound processing - a modulator that increases the gain of principal neurons, but reduces the gain of interneurons.

    Combined transcranial magnetic stimulation and electroencephalography reveals alterations in cortical excitability during pain

    Nahian Shahmat Chowdhury, Alan KI Chiang ... Siobhan M Schabrun
    Combined TMS-EEG can be used to further elucidate the mechanisms for pain perception and to discover biomarkers for the development of chronic pain.

    Loss of cortical control over the descending pain modulatory system determines the development of the neuropathic pain state in rats

    Robert AR Drake, Kenneth A Steel ... Anthony E Pickering
    Alterations to brain network communication leading to a progressive loss in descending inhibitory modulation of the spinal cord is a key determinate of pain state development following peripheral nerve injury.

    Perineuronal nets control visual input via thalamic recruitment of cortical PV interneurons

    Giulia Faini, Andrea Aguirre ... Alberto Bacci
    Accumulation of perineuronal nets around parvalbumin (PV)-positive inhibitory interneurons closes visual cortical plasticity by selectively down-regulating thalamic synapses onto PV cells in a sensory-dependent manner.

    Heterozygous expression of a Kcnt1 gain-of-function variant has differential effects on somatostatin- and parvalbumin-expressing cortical GABAergic neurons

    Amy N Shore, Keyong Li ... Matthew C Weston
    An epilepsy-associated potassium channel variant causes neuron-type-dependent alterations in ionic currents, neuronal excitability, and network connectivity.

    Complex pattern of facial remapping in somatosensory cortex following congenital but not acquired hand loss

    Victoria Root, Dollyane Muret ... Tamar R Makin
    Both hand and face representations remain relatively stable after arm amputation in adulthood, with no link to phantom limb pain, whereas pre-natal limb loss triggers complex patterns of remapping that do not relate to cortical topography.
    1. Neuroscience

    Fast-spiking GABA circuit dynamics in the auditory cortex predict recovery of sensory processing following peripheral nerve damage

    Jennifer Resnik, Daniel B Polley
    Dynamic regulation of feedforward inhibition from parvalbumin-expressing inhibitory neurons is linked to the gradual restoration of cortical sensory processing following auditory nerve damage.

    Neuro-evolutionary evidence for a universal fractal primate brain shape

    Yujiang Wang, Karoline Leiberg ... Bruno Mota
    Cortices from 11 primate species share the same archetypal fractal shape, indicating a universal mechanism for primate and mammalian cortical folding, and suggesting novel shape biomarkers for brains.

    Widespread nociceptive maps in the human neonatal somatosensory cortex

    Laura Jones, Madeleine Verriotis ... Maria Fitzgerald
    Widespread somatosensory cortical activation following a single localised skin breaking procedure indicates a diffuse pain map in the human infant brain.
    1. Neuroscience

    A novel inhibitory nucleo-cortical circuit controls cerebellar Golgi cell activity

    Lea Ankri, Zoé Husson ... Marylka Yoe Uusisaari
    The glycinergic neurons of the cerebellar nuclei project extensively to the cerebellar cortex and inhibit GABAergic Golgi cells.
