New fossil evidence from China suggests that some of our vertebrate ancestors had four eyes. The study, published in Nature, ...

This study reports important findings about the nature of feedback to primary visual cortex (V1) during object recognition. The state-of-the-art functional MRI evidence for the main claims is solid, ...

A recent study shows a new approach called Perceptual Attention Therapy (PATH) restores attention, memory and reading skills faster than standard therapies. Here, MEG brain imaging provides evidence ...

Summary: New research shows that the prefrontal cortex doesn’t simply broadcast generic commands to sensory regions—it sends finely tailored signals that shape how the brain processes vision depending ...

Each year, thousands of stroke survivors are left with hemianopia, a condition that causes loss of half of their visual field (the “vertical midline”). Hemianopia severely affects daily activities ...

Certain dogs can not only memorize the names of objects like their favorite toys, but they can also extend those labels to entirely new objects with a similar function, regardless of whether or not ...

PER-001, an endothelin-1 receptor antagonist, targets vasoconstriction, impacting ischemia, inflammation, and vascular leakage in diabetic retinopathy. The phase 2A study showed potential improvements ...

The melanopsin (OPN4) gene is crucial in visual and non-visual processes. Certain single-nucleotide polymorphisms (SNPs) of this gene have been linked to altered light sensitivity, photoentrainment, ...
