Diabetic retinopathy occurs when diabetes is not properly managed and is now the leading cause of blindness in patients between 25 and 74 years […]
The precise wiring of our visual system depends upon the pattern of spontaneous activity within the brain that occurs well before birth, a new study by Yale researchers shows. “It isn’t just the genes. What happens within the womb is crucial,” said Michael Crair, the William Ziegler III Associate Professor of Vision Research at Yale […]
Researchers directed by Dr. Laurent Mottron at the University of Montreal’s Centre for Excellence in Pervasive Development Disorders (CETEDUM) have determined that people with autism concentrate more brain resources in the areas associated with visual detection and identification, and conversely, have less activity in the areas used to plan and control thoughts and actions. This […]
Elderly adults can improve their vision with perceptual training, according to a study from the University of California, Riverside and Boston University that has implications for the health and mobility of senior citizens. The study, “Perceptual learning, aging, and improved visual performance in early stages of visual processing,” appears in the current online issue of […]
