Have you ever wondered how that mushy glob of tissue –– producing your every thought, action, and emotion –– is built? In this episode, we sit down with Jeffrey Macklis, a professor in Harvard’s Department of Stem Cell and Regenerative Biology and Center for Brain Science, to tackle gripping questions about how the brain develops and what happens when things go wrong in cases of disease and disorder. Tune in if you’re curious about how sets of genes can orchestrate brain development with remarkable precision, and about the potential to apply this innovative research towards regeneration and repair of the human brain. Presented by the Harvard Crimson. Hosted by Katelyn Li and Sanjana Narayanan. Produced by Amanda Su. Podcast art by Margot Shang.
