Researchers at Johns Hopkins University have discovered that surviving neurons in the visual system can sprout new branches to rebuild connections with the brain after traumatic injury, restoring function without regenerating lost cells. The process, observed in mice, proved effective but slower in females, highlighting sex-based differences in recovery. This finding challenges long-held beliefs about neural regeneration and offers insights into human brain injury treatment.
