    Causal role of the frontal eye field in attention-induced ocular dominance plasticity

    Fangxing Song, Xue Dong ... Min Bao
    A series of experiments suggest that the fronto-parietal attentional network is involved in controlling eye-based attention, and FEF plays a crucial causal role in generating the attention-induced ocular dominance shift.

    Thalamic regulation of ocular dominance plasticity in adult visual cortex

    Yi Qin, Mehran Ahmadlou ... Christiaan N Levelt
    Inhibitory innervation in the dorsolateral geniculate nucleus is crucial for adult thalamic and cortical ocular dominance plasticity, highlighting potential thalamic involvement in conditions like amblyopia and learning disabilities.
    1. Neuroscience

    Contrasting roles for parvalbumin-expressing inhibitory neurons in two forms of adult visual cortical plasticity

    Eitan S Kaplan, Sam F Cooke ... Mark F Bear
    Parvalbumin-containing inhibitory neurons are crucial for expression of plasticity in adult visual cortex that supports visual recognition memory, but not for expression of ocular dominance plasticity that results from monocular deprivation.

    Pull-push neuromodulation of cortical plasticity enables rapid bi-directional shifts in ocular dominance

    Su Z Hong, Shiyong Huang ... Alfredo Kirkwood
    Neuromodulation of the expression of Hebbian plasticity enables rapid cortical sensory-induced remodeling in post-critical period adults, and can rescue deficits induced by prolonged sensory deprivation.

    Ocular dominance-dependent binocular combination of monocular neuronal responses in macaque V1

    Sheng-Hui Zhang, Xing-Nan Zhao ... Cong Yu
    Binocular combination of monocular neuronal responses involves response suppression for neurons more preferring one eye and response enhancement for neurons more preferring both eyes in macaque V1.

    Internal neural states influence the short-term effect of monocular deprivation in human adults

    Yiya Chen, Yige Gao ... Jiawei Zhou
    Having the eye open under the patch, even though this does not change the exogenous stimulation because the eye is occluded, will result in an enhanced short-term effect for ocular dominance due to the internal neural states.
    1. Neuroscience

    Light reintroduction after dark exposure reactivates plasticity in adults via perisynaptic activation of MMP-9

    Sachiko Murase, Crystal L Lantz, Elizabeth M Quinlan
    Light reintroduction (LRx) after dark exposure reactivates structural and functional plasticity in the adult mouse visual cortex by increasing the activity of MMP-9 at thalamo-cortical synapses.

    Mutual interaction between visual homeostatic plasticity and sleep in adult humans

    Danilo Menicucci, Claudia Lunghi ... Angelo Gemignani
    The study of sleep following monocular deprivation has shown that sleep slow oscillations and spindles occurring during non-REM sleep have a role in homeostatic ocular dominance plasticity even in the adulthood, beyond synaptic homeostatic hypothesis that applies to Hebbian phenomena.
    1. Neuroscience

    Sensory experience modifies feature map relationships in visual cortex

    Shaun L Cloherty, Nicholas J Hughes ... Michael R Ibbotson
    A new form of brain plasticity extends the known limits for how much early sensory input can alter the brain.
    1. Neuroscience

    Response to short-term deprivation of the human adult visual cortex measured with 7T BOLD

    Paola Binda, Jan W Kurzawski ... Maria Concetta Morrone
    Two hour deprivation of vision in one eye transiently boosts the representation of the deprived eye (suppressing the non-deprived eye) in adult human V1 and along the ventral pathway.
