Whether we’re staring at our phones, the page of a book, or the person across the table, the objects of our focus never stand in isolation; there are always other objects or people in our field of ...

Neuroscientists have artificially increased neuronal activity in part of the brain by briefly shining light on genetically modified neurons. They saw that this manipulation selectively enhanced ...

Researchers at The Picower Institute for Learning and Memory at MIT report that Alzheimer’s disease disrupts at least one form of visual memory in mice by degrading a newly identified circuit that ...

Our eyes are continuously bombarded by an enormous amount of visual information—millions of shapes, colors, and ever-changing motion all around us. For the brain, this is no easy feat. On the one hand ...

Scientists have integrated human brain organoids into the brains of rats with injuries to their visual cortices and gotten the cells to respond to stimulation, according to a new study from ...

When you see a bag of carrots at the grocery store, does your mind go to potatoes and parsnips or buffalo wings and celery? It depends, of course, on whether you're making a hearty winter stew or ...

Even mild head injuries can mean serious consequences for brain function at its most basic level. Research published in Communications Biology shows that neuroplasticity, too, has its limits. Injuries ...

Visual auras, like those that occur in migraines, may be signs of small injuries to the brain’s visual cortex, according to a clinical trial at UC San Francisco that tracked the appearance of these ...

Catheter ablation procedures involving transseptal puncture — typically used to treat atrial fibrillation — are often linked to migraine-like visual auras, though the underlying cause has been unclear ...
