Which parts of brain can you live without?

You can't live without any part of the brain. But is possible for one side of the brain to live without hearing which is deafness and by the way you should not try to switch brains with any-body beacause there's 1-1,000,000 you will not survive.it is most likely that if you try and remove a part or if a part of your brain des you might die so be careful with what you do and if neurons die they won't come back like when your skin heals this is because of the connections when your born.
