Songbird study reveals potential paths for human brain’s self-repair, neurogenesis

Boston University researchers found that adult-born neurons in zebra finches can migrate by tunneling through existing brain tissue.

The discovery challenges the long-held idea that glial scaffolds are required for neuronal migration during neurogenesis.

Published in Current Biology, the study offers a new model for how fresh neurons may integrate into adult brains.

The findings could help guide future research on human brain repair, regeneration, and neurodegenerative disease treatments.
