Classification of Visual Cortex Plasticity Phenotypes following Treatment for Amblyopia
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
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
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
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.
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. …”
