➀ Researchers at the Vienna University of Technology investigated the retinal neurons of blind mice using microelectrodes, revealing a stable behavior that is promising for retinal implantation. ➁ The study shows that retinal ganglion cells can take on different roles and perform individual tasks for vision, even when parts of the retina degenerate. ➂ The findings are significant for the development of retinal implants that aim to restore vision in blind patients through electrical stimulation.
