Neuroscientists have identified the location in the brain's visual cortex responsible for generating a common perceptual illusion: seeing shapes and surfaces that don't really exist when viewing a fragmented background.
Blurred images that are unidentifiable as still pictures become understandable once the images are set in motion. That’s because of a phenomenon called "optic flow"—which may be especially relevant as a source of visual information in people with low vision, reports a study ‘With an Eye to Low Vision: Optic Flow Enables Perception Despite Image Blur’, (published online ahead of print, September 3, 2013) in the October issue of Optometry and Vision Science official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

The team gave the drug a biodegradable coating to keep it in the eye longer. If effective in humans, monthly needle sticks to the eye, which are the current standard of care, could be replaced with only two or three injections per year.
