Aerobic Exercise Effects on Ocular Dominance Plasticity with a Phase Combination Task in Human Adults [PDF]

Neural Plasticity, 2017
Several studies have shown that short-term monocular patching can induce ocular dominance plasticity in normal adults, in which the patched eye becomes stronger in binocular viewing.

Monocular delay during visually guided actions is as effective as monocular deprivation in driving ocular dominance plasticity [PDF]

Scientific Reports
In normally sighted adult volunteers, applying a monocular patch for a few hours produces a short-term shift of ocular dominance in favor of the deprived eye—a phenomenon often interpreted as a form of homeostatic plasticity.

The role of GluA1 in ocular dominance plasticity in the mouse visual cortex. [PDF]

J Neurosci, 2013
Ocular dominance plasticity is a widely studied model of experience-dependent cortical plasticity. It has been shown that potentiation of open eye responses resulting from monocular deprivation relies on a homeostatic response to loss of input from the closed eye, but the mechanisms by which this occurs are not fully understood.

Inhibitory maturation and ocular dominance plasticity in mouse visual cortex require astrocyte CB1 receptors [PDF]

iScience
Summary: Endocannabinoids, signaling through the cannabinoid CB1 receptor (CB1R), regulate several forms of neuronal plasticity. CB1Rs in the developing primary visual cortex (V1) play a key role in the maturation of inhibitory circuits.

Short-term ocular dominance plasticity is not modulated by visual cortex tDCS but increases with length of monocular deprivation [PDF]

Scientific Reports, 2023
Transcranial direct current stimulation (tDCS) of the occipital lobe may modulate visual cortex neuroplasticity. We assessed the acute effect of visual cortex anodal (a-)tDCS on ocular dominance plasticity induced by short-term monocular deprivation (MD),

Non-Synaptic Mechanism of Ocular Dominance Plasticity. [PDF]

ASN Neuro
Abstract Classic experiments showing that monocular visual disruption alters synaptic connections to binocular neurons established the fundamental concept of synaptic plasticity. Synaptic inputs that are activated coincidently with postsynaptic action potential firing are strengthened, and inputs from cells firing before or after the ...

The early stage of adult ocular dominance plasticity revealed by near-infrared optical imaging of intrinsic signals

NeuroImage, 2023
Long term monocular deprivation is considered to be necessary for the induction of significant ocular dominance plasticity in the adult visual cortex. In this study, we subjected adult mice to monocular deprivation for various durations and screened for ...

Pupillometry indexes ocular dominance plasticity

Vision Research
Short-term monocular deprivation in normally sighted adult humans produces a transient shift of ocular dominance, boosting the deprived eye. This effect has been documented with both perceptual tests and through physiological recordings, but no previous study simultaneously measured physiological responses and the perceptual effects of deprivation ...

Autophosphorylation of αCaMKII Is Required for Ocular Dominance Plasticity [PDF]

Neuron, 2002
Experience is a powerful sculptor of developing neural connections. In the primary visual cortex (V1), cortical connections are particularly susceptible to the effects of sensory manipulation during a postnatal critical period. At the molecular level, this activity-dependent plasticity requires the transformation of synaptic depolarization into changes

Ocular dominance plasticity: inhibitory interactions and contrast equivalence. [PDF]

Sci Rep, 2017
AbstractBrief monocular occlusion results in a transient change in ocular dominance, such that the previously patched eye makes a stronger contribution to the binocular percept after occlusion. The previously unpatched eye therefore makes a correspondingly weaker contribution to the binocular sum.
