The mind is what we perceive as our brain. The brain is the biological entity that allows this perception. They're not one and the same, but the mind depends on the brain, we don't know yet, but I'm inclined to think it depends COMPLETELY on the brain. Meaning no brain=no mind.
They don't need to be one and the same. And they're quite obviously not.
