"Recent scientific advances have meant that eyesight can be partially restored to those who previously would have been blind for life. " Tracking the evolution of crossmodal plasticity and visual functions before and after sight-restoration "Visual deprivation leads to massive reorganization in both the structure and function of the occipital cortex, raising crucial challenges for sight-restoration. We tracked the behavioral, structural and neurofunctional changes occurring in an early and severely visually impaired patient before, 1.5 and 7 months after sight restoration using magnetic resonance imaging."
