Researchers Restore Sight in Blind Rodents

A team of neuroscientists and bioengineers from MIT’s Department of Brain and Cognitive Sciences and Center for Biomedical Engineering have been able to partially restore the vision of rodents whose visual neural pathways had been severed by injecting them with a tiny, biodegradable substrate on which brain cells were able to regrow and reconnect. The …

How the Brain Reassembles Visual Input

It happens automatically and so quickly that most people probably never question the process of vision. Although it starts with the eyes, the majority of the work is performed in stages by cooperating layers of neural regions in the brain. As such, the underlying mechanism behind seeing and recognizing objects has long been of interest …

New Machine Vision Algorithm for Depth Perception

Although there have been many advances in machine vision, most relatively simple robots are still not able to maneuver around objects at high speeds because they are unable to quickly judge their distance from the objects. In order to tackle this problem researchers from Stanford University have developed a new algorithm that many said was …

Scientists Decipher Visual Neural Output

Visual Neural Patterns

MIT has published a news release about how neuroscientists in the McGovern Institute for Brain Research have recently made significant advances in their attempts to learn how the inferotemporal (IT) cortex identifies and categorizes visual data. The ability to visually recognize objects, while usually taken for granted because it happens quickly, automatically, and subconsciously, is …

Rice University Blindsight Study

The Human Eye

LiveScience.com has a summary of a study published this week in the online edition of Proceedings of the National Academy of Sciences that provides additional evidence of the phenomenon known as blindsight, residual visual sensitivity experienced in the brain even when one is blind or otherwise unable to see. While the results of the study …
