A new design for eye and brain implants draws its inspiration from nature. UO researchers have grown rodent retinal neurons on a fractal-patterned electrode, one that mimics the repeating branching pattern in which neurons naturally grow. It’s a step closer to making a bio-inspired bionic eye, a longstanding goal for UO physicist Richard Taylor. Taylor hopes the tiny electrodes could someday be implanted into the eye to restore sight in people with macular degeneration or other vision disorders.
