These scientists wanted to see if they could use electronic pills that you can swallow to help change how the brain works without needing surgery. They gave these special pills to some people and then used them to send signals to their brains to see if it would make a difference. They found that the pills were able to change how the brain worked without any need for cutting the body open.
