One of the more studied parts of the human anatomy, the retina—the neural layer at the back of the eye that senses light—still has secrets to reveal.
“Researchers have known for decades that increased levels of light increase visual acuity,” said Erika Eggers, assistant professor of biomedical engineering, physiology and neuroscience and member of the BIO5 Institute at the University of Arizona. “But we still don’t understand the mechanisms behind this process. It seems like it should be relatively simple, but it’s really very complicated.”
