Summary: Researchers have discovered that the human retina synchronizes visual signals before they even reach the brain. By adjusting the diameter of nerve fibers, longer retinal axons transmit signals faster, ensuring they arrive in near-perfect sync with shorter ones. This process reduces timing differences to just milliseconds, preserving a unified visual experience. The finding challenges the long-held assumption that such …
