We put a lot of the research for this documentary into this 3-dimensional software program called Personal Brain. It is a work-in-progress as we digitize the piles and boxes of highlighted articles and books that we used. We also plan to expand this web of information to include articles and research from you, our interdependent participatory audience. Please email us ( if you have an article you think we should include. Our Facebook page is also a great place to stay posted on current research — our team and our community are always adding interesting new “salty nuts,” as we call them.
