What Growing Mini Brains Has Taught Us, And What's Next

Organoids are miniature human organs grown in labs, with mini brains being the most intriguing. They replicate some 3D features of human organs, aiding research in conditions like microcephaly, autism, and the Zika virus. Despite their potential, organoids face challenges like size limitations and lack of blood vessels. Future advancements may address these issues, but ethical concerns about consciousness and sensory capabilities remain.
