Story summary

Male mice restored visual connections faster than female mice after eye injury.
Researchers at Johns Hopkins University in Maryland reported surviving eye cells sprouted new branches, reestablishing nearly all neural connections.
They observed that neurons did not regrow, but the sprouting compensated for the damage.
Lead author Athanasios Alexandris said the findings, published in February 2026 in the Journal of Neuroscience, may guide recovery from traumatic brain injuries.
