We all heard and told the stories that someone's brain is in their...well you know.  We may not have been that far of after all.  Scientists in Australia now say that human beings have a second brain, and it's in our butt!

The Inquisitr says the research was originally done to find ways to treat constipation and irritable bowel syndrome.  They found a nervous system that controls  muscle movement in the colon independently of the central nervous system, and scientists say they think learning how this works could also lead to new ways to treat depression and anxiety.

By the way, they think this second brain was probably developed before the central nervous system so it may actually be our first brain.
