Scientists have long been working toward a day when a traumatic injury or stroke doesn’t cause brain cells to be permanently lost.

Executing this extremely difficult task would involve figuring out how to transplant new neurons into brain tissue. But neurons form precise connections with each other, and are guided by physiological signals that are active during early brain development ― meaning that you can’t sow a fistful of new neurons into mature brain tissue and expect them to grow the way they should.
