    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. …”

    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. …”

    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. …”

    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. …”

    Gustatory-Visual Interaction in Human Brain Cortex: fNIRS Study by Karolina Jezierska, Aneta Cymbaluk-Płoska, Justyna Zaleska, Wojciech Podraza

    Published 2025-01-01
    “…Background: Many studies, for example, on taste-visual dissonance, have shown that the influence of the visual cortex on taste sensation is enormous. The presented work aims to investigate, using fNIRS, whether a taste stimulus, in this case, the taste of bitter, also causes stimulation of the visual cortex in the fNIRS study. …”
