Question

Can some one survive on half brain and how?

Answer 1

There are a surprising number of known cases of people missing halfof their cerebral cortex—the outermost chunk of brain tissue. A currently living and healthy 16-year-old German girl is one. She was born without the right hemisphere of her cortex, though this wasn't discovered until she was 3 years old.

Answer 2

Yes, hundreds of people have survived in the past with only half of their brain. In a process known as Hemispherectomy, one hemisphere (half) of the brain is surgically removed.

Hope this will help you!!!
