Summary: Scientists have discovered that neural stem cells (NSCs) receive constant feedback from their daughter cells, influencing whether they remain dormant or activate to form new neurons and glia. This parent-child relationship helps regulate brain regeneration and repair.

The study also reveals that calcium signaling plays a key role in how NSCs decode multiple signals from their environment. If NSCs produce only a few daughter cells, they activate; if they produce many, they stay dormant.

These findings challenge previous assumptions that NSCs function independently and open new avenues for treating neurodevelopmental disorders. Future research will explore how these processes change in aging and disease.
