Eyes Connect within Mouse Brain (image) NIH/National Eye Institute Caption To trace the connections of the eyes to the brain in a mouse, different dyes can be placed into each eye. The left eye (red) and right eye (blue) mostly connect in separate territories. But they can both connect to the binocular zone (green-yellow). Amblyopia occurs when one eye is impaired and the other takes over this zone. Credit Image courtesy of Dr. Joshua Trachtenberg, UCLA.
