 Okay, brains they are very complex the world doesn't even barely know have of what the brain can do. For instance, the brain figures out how to hear even if you don't have this special bulb thing in your brain. they are big enough to be seen from an MRI but they did a test that specifically saw that there were three women out of one thousand. That could hear and they didn't have this bulb thing in their brain so scientists have figured that the bulb is either too small to be seen or isn't there. And the brain is using another part of their brain to be able to hear but either way, you can see how resourceful your brain is.
