Triune brain

The triune brain is a way of understanding the different parts of the brain. It's like splitting the brain up into three parts. The first part is the oldest part and is called the 'reptilian brain.' This part helps us with basic things like breathing and keeping our heart beating. The second part is called the 'limbic brain' and it controls our emotions and helps us remember things. The last part is the 'neocortex' and this is the most recently evolved part. This is the part we use to think and understand complicated things. We wouldn't be able to walk, talk, or do math without this part. So the triune brain is just an easy way to remember all the different things our brain can do.
