Beyond Sight: Unraveling the Mysteries of Brain Wiring

Posted by in categories: genetics, neuroscience

Summary: Scientists made a novel discovery using zebrafish with a genetic mutation. These ‘deep-blind’ fish lack connections between the retina and brain yet retain functional brain circuits.

Remarkably, despite their inability to see, direct brain stimulation through optogenetics triggers normal visual behavior. This suggests that much of the zebrafish brain’s wiring is innate and doesn’t rely heavily on visual experience.
