Scientists have discovered that after injury, the visual system can recover by growing new nerve connections instead of replacing lost cells[1]. Surviving eye cells formed additional branches that restored communication with the brain[1]. These new pathways functioned similarly to the original neural connections[1]. The restoration process led to the return of part or all of the vision in the studied subjects[1]. In women, the repair process was slower or incomplete compared to men, suggesting biological differences in recovery[1]. The paper cites these findings as the main results of the study and describes the branching mechanism of surviving cells as the cause of reconnection with the brain[1].
