Age-related macular degeneration (AMD), affecting the retina, afflicts one out of ten people
aged 80 years or older in the United States. AMD often results in vision loss to the central 15 …

Studies of the effects of peripheral and central lesions, perceptual learning and
neurochemical modification on the sensory representations in cortex have had a dramatic …

To evaluate the effects of perceptual learning on contrast-sensitivity function and visual
acuity in adult observers with amblyopia, 23 anisometropic amblyopes with a mean age of …

Retinal and cortical lesions are completely different events that trigger visual cortical
plasticity. We therefore compared the cortical effects of homonymous lesions of the central …

In adult songbirds, seasonal changes in photoperiod and circulating testosterone (T)
stimulate structural changes within the neural song control circuitry. The mechanisms that …

In primates, lesions of striate cortex (V1) result in scotomas in which only rudimentary visual
abilities remain. These aspects of vision that survive V1 lesions have been attributed to …

Right hemispheric brain damage is often accompanied by visual neglect of contralesional
hemispace as well as profound visuospatial and visuoconstructive disorders. Despite some …

In this, the post-genomic age, our knowledge of biological systems continues to expand and
progress. As the research becomes more focused, so too does the data. Genomic research …

Different intracortical mechanisms have been reported to contribute to the substantial
topographic reorganization of the mammalian primary visual cortex in response to matching …

We studied patient JS, who had a right occipital infarct that encroached on visual areas V1,
V2v, and VP. When tested psychophysically, he was very impaired at detecting the direction …
