Scientists Discover “Gorditas” and Other Novel Brain Cell Types
Amanda Heidt | Jun 10, 2021
A pool of neural stem cells that ordinarily lies dormant in the brains of adult mice spawns two types of never-before-documented glial cells when artificially reactivated, potentially pointing to a novel mechanism of brain plasticity.
