    Classification of Visual Cortex Plasticity Phenotypes following Treatment for Amblyopia by Justin L. Balsor, David G. Jones, Kathryn M. Murphy

    Published 2019-01-01
    “…Monocular deprivation (MD) during the critical period (CP) has enduring effects on visual acuity and the functioning of the visual cortex (V1). This experience-dependent plasticity has become a model for studying the mechanisms, especially glutamatergic and GABAergic receptors, that regulate amblyopia. …”

    Aerobic Exercise and Human Visual Cortex Neuroplasticity: A Narrative Review by Dania Abuleil, Benjamin Thompson, Kristine Dalton

    Published 2022-01-01
    “…There is compelling evidence from animal models that physical exercise can enhance visual cortex neuroplasticity. In this narrative review, we explored whether exercise has the same effect in humans. …”

    BACE1 Is Necessary for Experience-Dependent Homeostatic Synaptic Plasticity in Visual Cortex by Emily Petrus, Hey-Kyoung Lee

    Published 2014-01-01
    “…We previously reported that Arc is critical for sensory experience-dependent homeostatic reduction of excitatory synaptic transmission in the superficial layers of visual cortex. Here we demonstrate that mice lacking the major neuronal β-secretase, BACE1, exhibit a similar phenotype: stronger basal excitatory synaptic transmission and failure to adapt to changes in visual experience. …”

    Potential Role of Synaptic Activity to Inhibit LTD Induction in Rat Visual Cortex by Matthew R. Stewart, Hans C. Dringenberg

    Published 2016-01-01
    “…Under these conditions, LFS applied to the lateral geniculate nucleus resulted in LTD of field postsynaptic potentials (fPSPs) recorded in the primary visual cortex (V1). Pairing LFS with stimulation of the brainstem (pedunculopontine) reticular formation resulted in the appearance of faster, more complex activity in V1 and prevented LTD induction, an effect that did not require muscarinic or nicotinic receptors. …”

    Early life stress shifts critical periods and causes precocious visual cortex development. by Janet Poplawski, Tony Montina, Gerlinde A S Metz

    Published 2024-01-01
    “…Here we show that early-life stress (ELS) in mice shifts the timing of critical periods in the visual cortex. ELS induced by animal transportation on postnatal day 12 accelerated the opening and closing of the visual cortex critical period along with earlier maturation of visual acuity. …”

    IGF-1 Restores Visual Cortex Plasticity in Adult Life by Reducing Local GABA Levels by José Fernando Maya-Vetencourt, Laura Baroncelli, Alessandro Viegi, Ettore Tiraboschi, Eero Castren, Antonino Cattaneo, Lamberto Maffei

    Published 2012-01-01
    “…Exogenous administration of IGF-1 in the adult visual cortex, indeed, restores the susceptibility of cortical neurons to monocular deprivation and promotes the recovery of normal visual functions in adult amblyopic animals. …”

    APOE4 and sedentary lifestyle synergistically impair neurovascular function in the visual cortex of awake mice by Silvia Anderle, Orla Bonnar, Joseph Henderson, Kira Shaw, Andre M. Chagas, Letitia McMullan, Alexandra Webber, Kirsty McGowan, Sarah L. King, Catherine N. Hall

    Published 2025-01-01
    “…Using in vivo two-photon microscopy and haemodynamic measures, we record neurovascular function from the visual cortex of physically active or sedentary mice expressing APOE3 and APOE4 in place of murine APOE. …”

    Alice in Wonderland Syndrome: Localising insights from right visual cortex stroke complicated by epilepsia partialis continua by Gashirai K. Mbizvo, Viraj Bharambe, Brython Hywel, Shubhabrata Biswas, Andrew J. Larner

    Published 2025-03-01
    “…We present a case of Alice in Wonderland syndrome in association with a right posterior/visual cortex infarction with subsequent seizures including focal motor status (epilepsia partialis continua), the latter a hitherto unreported association. …”

    The Generation and Modulation of Distinct Gamma Oscillations with Local, Horizontal, and Feedback Connections in the Primary Visual Cortex: A Model Study on Large-Scale Networks by Chuanliang Han, Tian Wang, Yujie Wu, Yang Li, Yi Yang, Liang Li, Yizheng Wang, Dajun Xing

    Published 2021-01-01
    “…Here, we aimed to understand this question in a large-scale network model for the primary visual cortex (V1). We created a computational model composed of multiple excitatory and inhibitory units with biologically plausible connectivity patterns for RC, FF, FB, and HC in V1; then, we quantitated GAMMA in network models at different strength levels of HC and other connection types. …”

    Age-Dependent Switch of the Role of Serotonergic 5-HT1A Receptors in Gating Long-Term Potentiation in Rat Visual Cortex In Vivo by Peter J. Gagolewicz, Hans C. Dringenberg

    Published 2016-01-01
    “…The rodent primary visual cortex (V1) is densely innervated by serotonergic axons and previous in vitro work has shown that serotonin (5-HT) can modulate plasticity (e.g., long-term potentiation (LTP)) at V1 synapses. …”
