Scientists grew mini-brains in the lab from human stem cells. But here's the kicker: these tiny brain models unexpectedly developed eye-like structures! It was a real head-scratcher for researchers, who were initially just trying to mimic early brain development. This surprising twist shed light on the incredible complexity of brain development and raised intriguing questions about how organoids grow and organize themselves. Overall, it's a fascinating glimpse into the mysteries of the human brain.
