Human brains are difficult to observe because they are heavily protect by the skull and protective tissue, so scientists have struggled to understand how brains work. To help them learn more about brains, scientists have developed mini brains by creating organoids, a collection of lab grow neurons and other brain tissue. With the perfect combination of sugar, proteins, vitamins, and minerals the organoids develop into an early developing brain, called a mini brain. These mini brains function like human brains except they can’t think, reason, or develop consciousness because they aren’t organized the same way as real human brains. Mini brains also can’t interact with the outside world, but they are a helpful tool for studying development and disease, which will help us discover how the human brain is unique.
