Description: Episode 343
The task of growing human brains in a lab has taken a step forward. Scientists have been creating brain organoids since 2013, but have now grown blood vessels in them for the first time. These mini brains resemble the developing cortex - the area of the brain that thinks, feels and stores memories. These advancements will help us learn more about the brain and conditions like dementia. But what if we go too far and they become conscious?
