Stem cells are incredibly fascinating to look at. They possess the ability to turn into absolutely any cell in the body, performing any function. In a recent study done in Kyoto Univeristy, they were able to obtain a ball of pluripotent stem cells and place in a petri dish with liquid that was similar to the environment that a brain cells can grow in. They were able to grow the cerebral part of the brain and use it to assess the brain structures and measure activity in the neurons that were present. However, Yi Zhou from Florida State University said that the research had a long way to go since it only represented a part of the brain and not the whole organoid, and you could only measure the activity in certain neurons indirectly with calcium ion activity.
