How does ambidexterity affect brain function?

I don't think we know. I just read an article about handedness and brain lateralization. The scientist is conducting research in this area. He has a handedness survey that I am about to answer. I am posting his link at the bottom of this page. Oh and it is legit - a .edu site for Indiana U. He also has a link at the bottom of the page that might offer more info - Reasearch Guide.
