The amblyopic acuity deficit: impact on the identification of letters distorted by spatial scrambling algorithms

This study investigates how amblyopia affects letter identification in different spatial scrambling conditions, finding distinct patterns in the amblyopic eye compared to the fellow eye.

Stereo-anomaly is found more frequently in tasks that require discrimination between depths

This study finds that stereo-anomaly is more common in tasks requiring disparity sign discrimination than detection.

Metaplasticity: Dark exposure boosts excitability and visual plasticity in adult human cortex

The paper shows that brief dark exposure enhances cortical excitability and visual plasticity in adult humans through reduced intracortical inhibition.

The endogenous modulation of visual plasticity in human adults

This study shows endogenous factors significantly influence baseline contrast sensitivity and neuroplastic change in adult visual systems through neural oscillation modulation.

Exercise does not enhance short-term deprivation-induced ocular dominance plasticity: evidence from dichoptic surround suppression

This study tests whether exercise enhances ocular dominance plasticity induced by monocular deprivation and finds no such effect.

Integration of contours defined by second-order contrast-modulation of texture

This study investigates second-order contour integration in humans, finding reduced performance compared to first-order contours due to increased internal noise and lower efficiency.

Ocular Dominance Plasticity: Measurement Reliability and Variability

This study evaluates the reliability and variability of different methods for measuring ocular dominance plasticity after monocular deprivation.

Monocular vision is intrinsically unstable: a side-effect of binocular homeostasis

This study shows that monocular vision becomes unstable during eye deprivation, with contrast thresholds increasing over time, suggesting a slow build-up of changes in binocular circuits.

Visual plasticity and exercise revisited: no evidence for a \"cycling lane\"

The paper replicates a study on exercise's effect on visual plasticity in humans but finds no significant effect of exercise on ocular dominance shift during monocular deprivation.

Deficient stereopsis in the normal population revisited: why current clinical stereo tests may not be adequate

The study investigates why clinical stereo tests fail to detect a high percentage of stereo anomalies in the normal population compared to laboratory tests using depth sign judgments.

Inverse occlusion, a binocularly motivated treatment for amblyopia

This study shows that short-term inverse occlusion improves binocular balance, visual acuity, and stereo acuity in adults and older children with amblyopia.
