Artificial Retina Being Tested On Mice
2012-08-15 06:06:28

Connie K. Ho for redOrbit.com — Your Universe Online Researchers have developed an artificial retina with the ability to restore normal vision based on its work on deciphering the retina´s neural code for brain communication. It´s the first of its kind — an effective prosthetic retina device that can accommodate for blindness in mice. The results of the project are a major breakthrough in working to restore vision for the blind. To begin, the scientists from Weill...

Barrow Neurological Institute researchers Jorge Otero-Millan, Stephen Macknik, and Susana Martinez-Conde share the recent cover of the Journal of Neuroscience in a compelling study into why illusions trick our brains. Barrow is part of St. Joseph's Hospital and Medical Center in Phoenix. The study, led by Martinez-Conde's laboratory, explores the neural bases of illusory motion in Akiyoshi Kitaoka's striking visual illusion, known as the "Rotating Snakes." Kitaoka is a Japanese psychology...

How Your Eyes Deceive You
