Clinical trials: Occipital Cortex
Blindness
Brain Plasticity of Verbal Memory in the Blind
This study will examine whether blind people develop changes in the brain that improve memory function. Previous studies have shown that blind people, on average, perform better in memory tasks than sighted people.
